I looked into Disney Floral and Gifts while planning my proposal to my now fiancee. They were not really easy to work with and, as the PP mentioned, not cheap. They told me they couldn't really customize anything and they really seemed to be more interested in the sale than anything else.
Instead, I ended up contacting Betsy from Memories By Betsy, and she was an absolute pleasure to work with. She does completely customized baskets that can be delivered to your room (or if you are staying CL, it can be in your room when you arrive). I basically was able to talk to her about ideas of what to put into the basket or just chat about Disney in general. She was always quick in getting back to me (I had to take care of everything over e-mail since it was a surprise and my fiancee leaves for work after me and gets home before me). In the end I ended up spending about $230 or so including tax and delivery, the basket had a Jack and Sally doll, a Mickey trick or treat bucket, a light up ghost lanyard (as you can see I went with a Halloween theme) and inside bucket was a 5" glass slipper that said "Let's Live Happily Ever After", I also had a fresh bouqette of fresh flowers to go with the basket. The flowers were about $50 and the glass slipper was about $115, so that is where a bulk of my cost came from.
I would highly suggest getting in touch with Betsy before you make your decision on what to get and where from. She will duscuss some ideas and options and give you a no pressure quote. If you want, check out her site at memoriesbybetsy.com.
