I am so happy to find this thread. I have been struggling with ideas for the Welcome bag. My trouble is that it is a small wedding and most items are coming in stacks of 30 or 50! ha! I did find some cute tropical flower hair clips that change color in the sun from Del Sol. I love the idea of Spanish for Dummies book, and the aloe vera gel, pepto etc.
Does anyone know if you can find reasonably priced biodegradeable sunscreen in the US to give to the guests? We are doing a Tulum excursion, and this might be nice to provide to everyone before hand.
