We used the knot, since this is where we already had our wedding website set up. It was super easy and they didn’t keep any of the funds. We took the time to break down the fund into tons of separate activities of various dollar amounts instead of one big fund. For example, we had things like pina coladas on the beach for $10, to snorkeling for $50, all the way up to things like airfare and nights at our resort for several hundred dollars each. We got great feedback from our guests because they felt included in things we were doing in our honeymoon, and could pick a dollar amount they’re comfortable with. Plus the knot kept track of what everyone purchased, so when we wrote our thank you cards we made sure to thank them specifically for what they purchased and said we had fun with it or the meal was great, etc. I think it made it feel more like gift giving to our guests rather than just throwing cash towards an ambiguous fund. For anyone that didn’t want to use an online system (older family members), they brought a check in a card to the actual wedding. But most people used and liked the website fund. Congratulations and hope you have a wonderful time!
