Hi Melody!
Thanks for your great question! I'm loving the Dream Pass for Florida residents and I hope that it's as beneficial to you.
The base 4 day Dream Pass, currently advertised for $99 plus tax, only allows you one park admission per day. If you don't add the park hopper option to it, and you want to visit Epcot, you would need a separate admission. I think the the best way to stretch your dollar would be to add the hopper option to a Dream Pass (currently $26/Dream Pass. That is for all four days, not per day)
The Dream Pass tickets, (with the exception of some blackout dates
3/27 - 4/9/10), are valid until May 25th, 2010. You can see purchase information and prices from Disney's website on the Dream Pass
here (click the "buy now" button for price breakdowns). I'd also visit
this page on information on some other Florida resident special offers currently available as an fyi, particularly the Epcot after 4pm FL resident annual pass, and the FL resident Magic Your Way tickets.
I hope this helps you in planning your magical vacation! Come back to the Moms Panel should you need any more help!
