Welcome to our Cruise Reviews Forum. I've been on both the Allure and Oasis and found the disembarkation process to be much faster that any other terminal--less than 30 minutes. I wouldn't worry too much about getting to the car rental company, there's no penalty and you will still get a car if you happen to get there late. If you haven't done it already, I would advise you to go to Desk Relations and let them know you want early disembarkation.
I never would have known you didn't speak English if you didn't tell me. It looks like you speak better English than I do.
