Kara,
I booked my wedding at Dreams through DD as well. They actually gave me a contact for a TA and they are supposed to be really great at getting good deals. I have not contacted them yet, but I would get their info from Kristin if she hasn't not given it to you already. I have also been playing around on Expedia.com and have found on average it is around $600 per person for at least 4 nights. I am still researching the best way to get my guests the best price possible. I 'll definitely post if I find any better deals.
Please let me know if you come across any great deals as well!!
Good luck!
Brittany
