DF and I were thinking about May 2015 Wishes wedding as well, however the amount they wanted 3 months prior (February 2015) was a bit steep.
Timeline states:
"Second Payment is Due (payable by credit card, money order, or wire transfer). (75% of the Food & Beverage Minimum (plus service and taxes) For your estimated guest number, plus the enhancement minimum, plus the ceremony fee, minus the amount of the Non-Refundable Deposit previously paid by you.)" Which is usually 3,000 of the 4,000 minimum.
Just something to think about. But if doable, I say go for it! DF and I are planning our August 25 2015 wedding now
