Do-it-yourself US honeymoon!
If your honeymoon is red (roses), white (dress) and (something) blue, then check out this comprehensive site called TripCart. It covers a huge range of destinations in the US, including a great Hawaii section. They say “Finding romance in Hawaii is like finding sand on the beach”. Plus it lists can’t-miss activities for your destination that you can include in your registry if something strikes your fancy. Need ideas? Check out the romance tab on their homepage for some great honeymoon destinations or just click on the map region where you want to go. Be sure to take the tour, which shows you how to put together an itinerary easily. Then, of course, go to Smart Honeymoon and add those items to your registry.
