Sailed the Oasis of the Seas for one week. Have cruised several times but never during the fall. Ship was not overly crowded with slightly less than 6000 passengers. However, that was a lot for me!
PROS
With several distinct entertainment and activity areas you will never run out of things to do. There is a Sports Area with 2 Flowriders for surfers, basketball court, mini golf course, etc. There are several pools with those designated for adults only and children. Never had trouble getting a pool chair where desired.
ROOM: 11318. Good quiet location toward the back of the ship. Fairly spacious veranda room facing the outside port side. Bathroom is tiny and don't think several guests can take a shower in the average one. Can't fit more than one person at a time in the bath room. Did not have a storage problem but don't bring excess luggage.
