We worked through a customs broker that the hotel uses. It was not the cheapest option to send our favors, but as long as they are there when we arrive on June 29th, I'll feel like it was worth it. We also had trouble picking favors that would pass customs and be useful and easy to carry home. We ended up doing plastic logo'd beverage cups from Customink, Bottle Coolers that flatten with our logo (used a promotional agency), coral (resin) bottle stoppers (from weddingstar.com), pepto, advil, altoids, sunscreen and lip balm (all from amazon.com). We are also using coral (resin) place card holders and straw fans as decor that guests can bring home.
