First, don't freak. I promise you that everything will go wonderfully and you're freaking for no reason. Just be excited!! Grooms. They can be picked up in the trolley car prior to it getting you, or they can choose to walk. It'll depend on your photographer too. For instance, when I photograph weddings at the GBP, I take pictures of my grooms ahead of time, so it makes more sense for us to walk to the ceremony ourselves. It allows for great pictures of the groom with his groomsmen. The entire group will be spread out, but they do try to keep them within a few buildings of each other. It's nice to have some privacy, yet not have to walk all over the place. I have had brides who went to Walmart in Playa and had their own champange to toast with beforehand. I've also had a lot of my brides have it in their room as a present from the resort. For guests that are arriving at the same time as you, I'd hand them out then. Otherwise have a welcome dinner at the buffet on the first or second night and hand them out there.
