When we went in and met with our EM the first time, we told her what our budget was. But, in the planning, we threw it to the wind. We planned the "perfect" wedding with all the upgrades and extras we thought we might possible want. After we got the BEO and budget, we sat down together and starting nixing things that weren't important to us but that would have been wonderful in an ideal world- the $4.00/each tuxedo folded napkins, the Rolls Royce, etc. There wer things I wouldn't budge on, things he wouldn't budge on, and things our parents wouldn't budge on. I suspect you planned the "perfect" wedding, too.
If you didn't, now would be the time to accurately review your guest count and what you can realistically afford. Take a look at the individual budgets (floral, photogrpahy, videography, etc) and see if you can make substitutions or use outside vendors that would bring down the price. For example, with your flowers, padding them out with greens and in-season floral will greatly reduce the cost. If you're not set on the time of the day of your wedding, you may be able to reduce the costs by choosing a lunch or brunch menu instead of a full dinner menu.
My best advice: Do not over-extend yourself on the ticket price of the wedding alone. There are 100s of other little things (that all cost money) that will go into your overall wedding budget. Some of the big ones are obvious- transportation to Florida, hotel nights while you're there, food/spending money. Others, alteration costs, accesories costs, tips, gown steaming, etc., are "hidden" but are very, very real.
