We're (DW and I) doing a 4-night on the Wonder in May. We pre-paid rainforest, and will pre-pay tips. We're doing Palo and the $32 pp snorkel/bike/float combo at CC. We have no plan to do shutters. We're bringing on liquor for mid-day and pre-dinner cocktails, though we'll probably buy a few drinks otherwise. We plan to do Key West on out own, and to stay on-board for Nassau. We're bringing cash for room service and extra tips.
All of that said, I had thought that $150/day would be more than enough. Am I underestimating my cost?
Easy to figure out:
tips $12x2x4=$96
CC $32x2=$32
Palo $20x2=$40
Lots of room for drinks or other things on a budget of $150x4=$600. Probably $300 will cover it all.
