oh the beaches are beautiful and to get them all to yourselves that is magical really, that rarely happens over here. One of my all time favourite beaches was on an island off Brazil called IIha Grande, it was so beautiful, I imagine it is a lot more built up but the sand was almost white and it was covered in Palm trees and coconuts as well, the snorkeling there was amazing. Looking all the updates of you roadtrip , much love to you xx
