Just got off Allure of the Seas on Sunday. Didn't notice any issues from the propulsion issue. We made an unscheduled stop in Grand Cayman for a medical emergency it did not effect our arrival time in Cozumel at all.
I just heard from another person who said they had official word that cruises on Oasis of the Seas are cancelled for the next three weeks. There will be a full refund plus a credit for another cruise.
