We sailed the week of Halloween this year. We traveled on the Allure a year ago and thought we would try the Oasis this time. We travelled with neighbors, 4 couples. Some of it was absolutely wonderful, and some things well, not much. I will hit on the items I think will interest most people.
Embarkation: was remarkably smooth. We had our paperwork filled out and ready. Probably not 20 mins overall. We arrived early (husband was anxious, always is) and were greeted warmly and other than having a large wedding party most of whom were day trippers and were put in line in front of us, the whole thing was painless.
Room: Large and comfy. Bed was awesomely cozy. Our room attendant was always on the job and most days our room was made up when we returned from breakfast. Even the bathroom seems larger than most ships.
Carbin was large and comfortable. We were able to walk around without bumping into furniture. The aquatheater suite are very noisy during the day. If you like to relax or nap in the afternoons - forget it. There is always something going on below you and the sound system is LOUD. We were also way at the end of the hallway. It was a long, long walk to our room each time. If we go on the Allure or Oasis I will choose an outside balcony a little closer to the elevators.
