Hi Marie,
I totally feel for you... I am also getting married in early May 2010 and I originally wanted to pre-book back in March/April as well, but because the prices I was quoted was much more than I wanted to pay, I am deciding to wait until the "posted/contracted" package prices come out... which kind of sucks because my guests want to know ASAP when to book time off but I don't want everyone to book at a higher price than they should have to.
I hope everything works out okay
