I used to belong to SE and it has many great offers. You can get the meal vouchers for Disney as well as some great gift cards. I always bought Red Lobster, Bennigans, etc and carried them in my purse so when we were out if we wanted to stop and eat we could use the cards and have a 20% savings.
You can also buy the cards for Planet Hollywood and HRC if you are going to hit Universal on your trip.
Other great saving are KB Toys, Target, Penney's. I bought an xbox a couple of years back with my $200 in gift cards and I got a $40 rebate which meant I really only paid $160 for it. Great deal I think.
