We are planning our packing for our upcoming Galapagos cruise in 2 weeks. On those mornings or afternoons that schedule an island walk and snorkeling, should we wear our swimsuit on the walk? or should we plan to wear shorts on the walk and then change into your swimsuit? Do you usually change somewhere on the island or go back to the Catamaran to change? I'm not sure that my wife would be comfortable wearing her swimsuit on the walks. How far from shore typically are the Catamarans?
