I am hoping sundresses will be formal enough since we are packing once for both Kauai and Mexico. Maybe I will pack one semi-formal short dress that I can wear to Palo and Formal night. If I had it my way I would just spend all my time in flip-flops and comfy summer clothes (this is why I love Kauai, you can go to the finest restaurants in flip-flops). Now to see if I can dig around for an old dress...
