This was my first cruise, so there will be no comparisons to other cruise lines, or ships. Fearing sea sickness as I am prone to motion sickness, I took two Bonine tablets daily and had no problems.
We arrived at the port early, and got on early....The Windjammer was open for lunch and after that we explored the ship till our room was ready. The sail-away was cool, not knowing what to expect.
The ship is a floating city! There was so much to do, a lot we didn't even get to do and some things we had no interest in (like the rock climbing wall, the ice skating, basketball, etc) but was nice to see them there for those who wanted to do those things. The entire ship is beautiful and kept very clean. Pools were nicely kept. The promanade area is beautiful. And there seemed to be alot going on in that area, between musicians, parades, sidewalk sales, etc.
Food at the Windjammer was plentiful, delicious... plenty of variety at breakfast and lunch. Didn't have any dinners there as we enjoyed the dining room very much. All dinners at the dining room were wonderful. The selection was decent and everything we received turned out to be delicious. Waiters and staff were so nice. They greet you by name every night after the first night. Before dinner on the first night we requested a table for one, just because we thought we would enjoy being alone, but they were unable to grant our request and it turned out that the two other couples at our table were very nice and we had a good time with them. We saw all types of dress in the dining room from jeans to very dressy. We went to Portifino's on formal night, so I can't comment on formal night, but I can say that Portifino's was absolutely wonderful (food, staff and atmosphere).
Drinks were easily accessible. Numerous bars located throughout the ship. No long lines or waits and I believe the ship was about at capacity. We did go for the soda package, but probably could have done without it.
The shows were very professional. Saw three comedians, two singing/dancing shows. They really put their heart and soul into those productions. We also saw a couple who's act was called The Majestic. They did acrobatics and were outstanding. The palace theater where these shows are held was large and modern, no small time operation.
The ice show was excellent too. You have to get tickets ahead of time. They are free, but they need to control the number of people who show up.
Our room was an inside stateroom and very small but like others have said, were were only there to change clothes and sleep. It was fine for us.
We were never able to stay awake to go to the midnight buffets, but saw them setting up and they seemd very good.
I'm sure I forgot things, but hopefully this will give you an idea of what is on the Explorer of the Seas. Would definitely recommend this ship. And hopefully we will do this again.
