DW and I booked the REAS for our May 22 Western Caribbean cruise. One of the main reasons was so we wouldn't have to worry about the ressie rush and also to pick our dining rotation. APLAPLA was pretty important to us as it made more sense to be in Lumiere's on Formal and Semi-Formal nights and to be in Parrot Cay on Mexicali.
I got the famous Debbie when I called and I agree she was great to work with.
I do recommend you call before leaving to verify your information. Debbie suggested I do but I forgot with all the craziness before we left. Well, we got a different rotation than we requested so there went not having to worry about getting in a line as soon as we boarded the ship. While there, we checked all our other reservations to make sure they were correct. Our friends who booked a REAS too had a mistake on one of their reservations.
We also found the confirmation for our couple's massage in our room was set for 9:15 PM instead of AM. A phone call cleared it up as just a typo but we shouldn't have had to worry about any of this as the early reservations was one of the reasons we paid for the package.
Overall, we are glad we did it as everything turned out good in the end after the few hiccups to start.
Also, one thing you might want to consider for the couple's massage that we didn't think about... we made our reservation for the last day at sea with the intent of getting us good and relaxed before flying home and getting back into the grind. We didn't realize how sunburned we would be at that point from all the snorkeling we did and it caused the massage to be a little uncomfortable for DW!
Have a great trip but don't forget to call ahead to confirm!
