Medications if you take them, an extra pair of good comfy walking shoes in case your first pair starts to give you blisters, continuous-spray sunscreen, sunglasses, flip-flops or slip-ons to wear out to your resort pool, swimsuit, aloe vera gel in case you do get a sunburn, addresses for sending postcards, quarters for the toll booths on the freeway if driving from the airport, a wad of ones and fives for tipping, a good paperback to read by your pool. I know I'm forgetting something, but that's a start.
