Travelers: My husband and myself (mid 50's - early 60's)- As others have previously said, check-in is extremely efficient. Getting there early is best. Early= 10:45 A.M. to 11:00 A.M.
Cabin: Deck 10 Boardwalk Balcony - Our cabin was fine for the two of us. Jesus was our cabin steward and did an awesome job. We spent some time in our cabin, but not much. Of course, the bathroom is small. We thought the storage worked well. There was plenty of room for all of our belongings. Don't overstuff the drawers. At the lower bottom of the desk cabinette there was a mesh covering and we could see where someone lost a scarf that went behind the drawer. About noise - We were 8 cabins in from the aft (back) of the ship. If you are noise-phobic, a Boardwalk Balcony may not be to your liking. There will be times of great activity going on which you can hear. We absolutely loved it. We had a great seat for any show happening in the Aqua Theater!
Shows:We booked everything online prior to going. All of our reservations were ready for us upon arrival at every show. While we heard complaints on ship concerning having to make reservations for each show, it is a very equitable way of handling being able to see the shows. You can get in 10 minutes prior by taking seats of those who are "no shows".
If one is noise phobic, a Boardwalk balcony might need some consideration. The Boardwalk area of the Oasis is a very active area of the ship. Being the home of the Aqua Theater makes the Boardwalk a very lively area. For us, that was something we really enjoyed about it. We enjoyed experiencing all of the activities. We could either go down and get involved or observe from afar. The room itself met all of our needs. We enjoyed having breakfast on the balcony, the flat-screen TV, and felt storage space was appropriate for the week.
