Thanks so much for the info. ESPECIALLY the part about the B's having a full length couch. I have back and joint problems and can't sleep laying down on a bed. At home I sleep in a recliner. At least if there is a full length couch I can usually manage to prop myself up enough to sleep. :D (You didn't happen to see any recliners on board did you?)
Anyway, I changed today from an A to a B and will use the extra $$'s for our pre-cruise stay on Bora Bora.
Thanks again.
