Just got off Oasis (1-5-12/20). Boarding process very quick, but the vehicle traffic around terminal is very, very slow. Facial recognition was operating upon return - - very quick. Biggest delay was moving crowds outside between terminal building and curb.
My wife and I just got off Oasis - Eastern Caribbean (1/5-12/20) and there were 2 different headliner shows. On Sunday, Ronn Lucas offered twice @ 8:30 & 10:30 and then a different headliner, Finis Henderson offered multiple times on Wednesday & Thursday. You can book second offering onboard. Both were very entertaining. Enjoy!
