Honestly, a lot of brides don't use the BDW (crazy, right?!!?). And as most of you know, when you sign up for a wedding you're presented with dinner options and it typically does not include the poolside reception. So I'm not actually sure how many know that it's even available. It doesn't seem like it happens very often, or often enough for me to remember, to our BDW brides. However, it's growing more and more popular as people are realizing how awesome it is (and it IS awesome) And they have enough pools, but I don't know if they have enough equipment??? I doubt it would affect the service they provide for you. They charge a vendor fee for a reason, so it's not like it's severly affecting them. And it's YOUR wedding day. Make sure it's exactly how you want it.
