I have tried Oasis last year and Allure this year. Both ships are identical except for some restaurants, shows. For me I prefer the Oasis since the service was more polished and they looked like they were happy to see you come aboard. From the time we entered Allure, the room steward already asked us for a tip upon entering. We had no problem with this, but did not expect him to be forward and abrasive. Izumi was nothing special and servings were sparse. Giovanni's table was great with its family style dining. Cupcake cupboard interesting, but nothing special. The shows also were shorter in Allure than the Oasis and the content was fair. Loved the Promenade, Central Park was great. The clubs had dancing which we loved. The Bolero was great with the Merengue queen.king from Canada/California, really great international standard technique; timing impeccable.
The stops at Bahamas (we went on our own to Atlantis via a local tour group on the port. FOOd quality was also different form both ships, with Oasis having a better food standard. Sales pitch on the land excursions were aggressive. Since we were with another couple that had done the cruises before we did they took us around. Lastly, there was a mixup in our seating where they placed us on the later dining but was booked on the earlier one. Female maitred solved everything and had us eating early. Table servers were good and attentive.
