Hey Ready glad you had a good cruise!!
I agree with you the towel system is no big deal, the spa prices are way too high and FLL port is easy.
Your question of RCI burn out....No I don't get burned out (not yet anyway). They should change up the menu I already know before the cruise that on day 1 I'll be having the onion tart etc.
It all depends on the cruiser some like to stick to the same cruiseline and some like to switch around. There is no right or wrong answer.
