Hopefully no rain in Tahiti, they have a lot of rock sidewalks and my shoes were like sliding on them when it was raining and I did fall a few times. The hotel we stayed at pre-cruise gave us big umbrellas to use while out for the day, but that did not stop my falling. I walk a great deal so I was not hurt, but a homeless man helped me up both times. Yes, there are quite a few homeless people that would really like to have your food storage containers you take home from restaurants.
