Well you could stay silent on it, but that could be interpreted that you are expecting gifts, which might be considered grasping after your guests have shelled out $thousands to share your day. Those who truly want to gift you, will do so even with a note from you/fiance not to. Personally, I think it's a trade-off -- you get the gorgeous, tropical wedding of your dreams surrounded by your closest family and friends, and you forgo the toasters, sheets and towels. OR, you fork out big bucks for a traditional at home wedding, but you get the toasters, sheets and towels. You can always get what you need to set up house a little at a time, but a destination wedding and it's memories are a once-in-a-lifetime event that you'll cherish more than a china setting, lol!
