I ordered it for my parents back in 2010 so it might have changed since then. The bag was nice. But it was just filled with water, soda, chips, pretzels, cookies. So on one hand it is $$$$ for just getting some snack food you might not even like or eat. But on the other hand you get a nice bag and a surprise waiting in your room (if they other members of your party don't know about it - they will be so surprised!)
For my family, I did the small blue mickey cooler with the treats - I think that was worth it since I use it all the time at home and it's a "memento" from the trip. And my family was surprised to see something waiting when we got back from the park. They can't put it in your room until after you've checked in so we went off to the park after we arrived and came back later that night and there it was.
I think this trip I will do a kids themed one now that my son is old enough to know what's going on! It may be pricey but I think the surprise is awesome!
(Oh - I did all this through the Disney Florist website - is that the one you were talking about?)
