We will be in Maui from May 28-June 2. I know this is a very general topic question, but I wanted to know what to pack. I prefer to pack light, so I want to know the necessities. I'm good with clothes, but wanted to know more about other accessories (ie, sandals, fanny packs, etc). I read in Maui Revealed that is best to have reef sandals? are these worth it? or would normal flip flops and sandals work?
