First-day food- depending on if you get on the ship early, I would recommend checking out the Windjammer, if you get on after 12 Windjammer will be packed, I would give Playmakers a try, (Try it during the cruise) really good wings
Bars- The Bamboo room is really cool and was never too crowded when I went in. Playmakers bar was crowded at night, my personal favorite would be the Schooner Bar, not crowded and nice performances
Shows- Did not see production shows, but saw comedians and ice show, definitely a must watch.
Do slides/Flowrider the first day- little to no lines, will be crowded for the rest of the cruise
Slides- Blue slide is faster and has a great view of the side of the ship over the ocean, Yellow is slower and has an ok view of the ocean
Do Skypad- make reservations early, will be very busy
You also don't have to wear vr goggles if you don't want to, I didn't and they let me bounce higher and had a great view of the ocean
The Quest- CD and staff make this Quest a lot of fun, definitely a must do
