We flew to San Francisco a few days early via Frontier Airline. With the changes in flying conditions, we were apprehensive, but Frontier was great, and we would certainly book them again. Flying is not what it used to be - but I would give them a strong B for the flight. We had booked at Harbour Court Hotel with Priceline. We booked early, so probably didn't get the best price - but Harbour Court provided everything we were looking for. Near the Ferry Building, and the Bay Bridge. They provided a hosted wine bar each evening, cookies and milk later in the evening, and coffee first thing in the morning. The rooms were small - but really got us ready for the cruise. Give them an A. We booked a city tour combo with Sausalito and Muir Woods. And we really lucked out for weather - we had great weather - clear - and were able to get some really great pictures of the Golden Gate Bridge, Alcatraz, and Sausalito. The second day we booked a wine country, wine tasting tour. This also was a good deal - the weather was cooler, foggy, couldn't see the Golden Gate Bridge - even as we were crossing it on our way to Napa. We tasted at Chandon, V Sattui, Rutherford and Andretti. Again we really lucked out, Mario Andretti was at the winery - so we were able to get his autograph and picture, also picked up some wine to bring aboard. Give both these tours an A. Friday is embarkation day. We walked from the Harbor Court to Pier 35, for our first view of Infinity. Our home away from home for the next 16 days. We walked back to the Harbor Court, and grabbed a cab for the transfer to the Infinity. Embarkation was a breeze. We arrived at just before 12 noon, and were onboard and having our first mimosas at just after 12:15. Earlier arrivals had to wait to board, but they had just started boarding when we arrived, and we breezed through the process. A solid A for embarkation. We went to our cabin and dropped off our stuff. We had a concierge class cabin mid ship with veranda. We usually book this cabin class, so no surprises for us. We asked for the feather pillows right away. John, our cabin attendant took care of that and all other requests quickly and efficiently. A+ for cabin service. We had late seating for dinner, and Paul, our waiter, took excellent care of us, with his able assistant Johny. Food is a very subjective thing, but we never left the table hungry, and Always found something we liked on the new menu. I have heard a few complaints about the beef, but I had it several nights and enjoyed a good piece of beef each time. Our table mates also selected beef most nights, and also stated they had good beef. DH usually goes for the fish, and he was happy with his selection. Paul did steer him toward the always available grilled salmon a few nights when the main menu selection wasn't the best. Louis was our sommelier, and he was right on target each night. He also found a few bottles of Malbec late in the cruise, and personally delivered to our cabin. Another A+ for dining room and service. We usually breakfast and lunch at the Windjammer, and they were OK. There were waiters standing by to offer assistance with trays, and tables were clean and available. We had eggs cooked to order, and omelets a few times - and they were good. I also tried the eggs benedict at the buffet - but the Hollandaise was cold. Our tablemates stated they asked for cranberry juice each day, and did get it each day - but a few days they had to ask 2 or 3 times - because the first person wasn't able to get it for them. B+ for buffet. I think the cheeseburgers at the grill are the best - off the chart A+, and the onion rings were better than I wanted them to be - I was really trying hard to limit my carb intake during the day. We skirted at least 3 hurricanes during the cruise - the ride was a bit bumpy, the seasick bags were out on the stairs. We had to pass up one of our ports of call because of the weather, Huelteco Mexico. Since the ship is our destination - we don't mind, and I didn't hear any complaints about missing the port. We did the bus, train, boat safari in Costa Rica. We bussed to a nearby river and boarded a flat bottom type of boat for a safari - we saw 35+ crocodiles, and many birds. But we ran aground on a sand bar. While speculating if we would throw someone overboard (for the good of the mission), the tide lifted us off the sand bar. Boat safari finished, we transferred to the bus, and traveled to the train. The train was an engine, a second car, and 2 passenger cars. We traveled through the rain forest, and the train derailed. That's when we found out what the second car was - it carried the rail repair equipment. This appeared to be a frequent occurrence. They were finally able to repair the track, and we finished this segment of the tour, back on the bus to return to the ship. We were about 1 hour late returning from this tour, but still well before the ship was leaving this port - so it's all good. Hard to grade this one - we certainly got everything the excursion promised plus extras. But I still give it a C - the excursion was not an exercise in creative writing. Disembarkation was delayed by about 1 hour. Communication is certainly an area that is not Celebrity's strong point. We were late leaving the ship, but were able to grab a cab to the airport in a timely fashion. I'd give this a D. We flew home on Spirit Air. They had recently converted from paper to e-tickets, and we were lost in the shuffle. But they did get us on the plane and home - so an E for effort. They charge for all luggage, early seat assignments, all refreshments during the flight. We love cruising - and believe any day at sea is better than a day anywhere else. Celebrity is providing us a good bang for our buck. End of sermon for the day. Overall Grade is a very solid A.
