First, I have to say thanks to everyone for all of the amazing information gained from this forum.
Realistically how many bottles of sunblock should I pack? Everyone has suggesting taking extra due to the exorbitant price of this item at resorts, but how much will two people use over 6 days? I was going to bring 2 bottles. Am in the ball park? Also, should I count on others asking to "borrow" some? Thanks in advance.
