ditto on bringing too many clothes...did better this time than last vacation...but still too much...spent almost every day in a bathing suit and a sarong...had several sarongs and just kept changing them...tied them up as a dress for evening dinners...all the clothes i needed could have fit in a carry-on bag! it's a VERY casual place.
could have used a small collapsible umbrella one day for the extreme heat/sun, lack of shade at times and no wind...but only one day...so not sure it's really worth bringing.
glad we had lots of aloe vera spray gel...cooling when you get too much sun...and lots of body lotion...great for dry skin after days of snorkeling...and small bandaids...used these again this year when lots of walking you're not used to produces blisters...this time it was my husband who needed them with his sandals rubbing!
also...bring a small pocket type notebook and pen to record the days events each evening...because you want to remember all the details when you write your trip report for us later!!
