We just got back yesterday from a great week on the Summit.
We are an all-adult family of 5 sailing with my Grandmother, making us 6 people between the ages of 20 and 79. We booked 3 "sweet sixteen" 2C balcony cabins for $749 through an online travel agency and they gave us $175 OBC plus an additional $80 when we elected travel insurance.
We got into San Juan on Friday morning after flying all night from San Francisco and checked into the Condado Lagoon Villas at the Caribe Hilton. We booked these rooms on Priceline using "Name Your Own Price" for $125. We think the high minimum price was due to the combination of spring break and the Ironman being that weekend. A quick nap in the room and then over to the beach bar for a lunch of salad and grilled mahi mahi. Expensive, but good. We spent the rest of the day on the lagoon beach. This is a protected area with no waves. Great for families with small children. Many people were snorkeling. While the rooms were basic, they were clean and convenient for a 1-night stay. The property was nice. The only "down side" was that the Villas are far away from the main hotel lobby and the beach and pool area. Dinner was at a forgettable restaurant in Old Town San Juan. We are limited when we eat due to my Grandmother being very picky. We tried to go to Ceviche 358, but she couldn't find anything there to order.
Extended balcony without an extended price! We could easily fit 6 chairs and 3 small tables on the balcony for dinner one night. This is the same as the other deck 6 balcony staterooms from 6035 and forward.
