Royal Caribbean treated us great! We were able to board about noon in San Juan and the on-boarding at that time was fast. We explored the ship and had our first on-board lunch in the Windjammer! After lunch we decided to find our cabin and were surprised how big it actually was. It is laid out very smartly. Here are some details for others- Window was actually large maybe 3' in dia, there was room to move on all sides of the bed (2 nightstands- great to hold books etc) lots of room for the suitcases under the bed. We had a small loveseat and table too! Large closet with shoe shelves, tie bar, and a long hanging side and a dual hanging side. The desk had 2 dual outlets (never needed the suggested extension cord- and it did have a hair dryer in the room. Desk had large drawers on each side. TV, small refrig, and some more cabinets above the TV. There were small shelves above the desk- and in the bathroom! Water on board was fine to drink, and the small shower had a clothes drying line- we brought clothes pins and it worked great. Our luggage arrived while we were still checking the room out.
We did the Mytime dining and really enjoyed the main dining room. We had a table to ourselves, and sometimes thought it would have been good to move about and meet others- but it seemed all seats were assigned. We liked the flexibility of when to arrive for dinner. We had the same waiter and assistant waited for the whole cruise- they were super. The food in the main dining room was very good with a nice selection of fine dining choices. We used the Windjammer for Breakfast and found it to be OK. It had all the food you would think of for a large breakfast buffet. It was like buffet food though- nothing special.
We went out at each port, so most of our days were off ship except our one cruise day. During the one day at sea we had wonderful sunshine (many days had rain or showers) so everyone was in a lounge in the sun. We maxed out on the sun by lunch time and did some of the ship activities. Climbing wall had almost no wait, we took a swing dance class (just one other couple so private lessons with the professional dancers from the production cast), and a video scavenger hunt (did some crazy stuff).
In the evenings we enjoyed some dancing. Lots of dance choices all with live music. Most sat and watched as we hit the floor but we didn't care...and are not all that good. Just know that all the alcohol on the ship is extra cost as are the soft drinks! We went to most of the big productions shows- mostly music and dancing- "Stage to Screen", Tony Tillman, The Unexpected Boys, "Vibe-Ology" and a variety show with David Morgan. I'd rate the shows as OK.
Other info for us first time crusiers- Lifeboad drill is the first night. Lots of hand sanitizer was available to keep us healthy, you get a "Seapass card"- logs you on and off the ship, and is your onboard credit card. You put out bags on Friday and get them back after you get off the ship just before customs. Off boarding times are preset depending on you flight times or if you are staying in port. Everything was very well organized.
