Hi there,
We''re using travelers joy because I found that the honeymoonwishes that is Disney sponsored is not customizable. Since I know Disney pretty well and know my guests would rather buy into something specific than general like plane tickets or the hotel I'd much rather pick specific experiences, restaurants etc and describe hey they are interesting to US rather than generic descriptions provided by Disney. This way we were able to add things like food and wine festival events, fishing, each of our planned ADRs etc. We will then send each guest that decides to give on our registry a picture postcard of us enjoying what they gave us. If you know a bit about Disney and what you'd like to do I say it's the way to go. There's also no credit card fee and there's just the standard one time fee that comes out after the fact so your guests aren't surprised with added fees.
Edit: that's just the registry though, were using the knot for our website
