OP I'm not sure if you can wait, but there is a
Lego store at a mall about an hour from me. I go there every Wednesday to pick the kids up (my mom is watching them 3 days a week over the summer to help us save on daycare and to spend some time with the boys). We ventured into the Lego store today for the 1st time.
I don't mind going there next week and taking pictures of the fill up tubs. The prices were 13.99 and 7.99. The prices were about the same as stores like TRU. They did have some stuff I've never seen in stores, as it was new.
Are you flying or driving to WDW? Will you have a rental car? If you have a car while there my suggestion would be to find a
Walmart, Target or TRU is the area and have him get the blue tub of Legos. It's about $20-$25 and has a small green flat plate, a door, windows. No people, but you can buy a small set for about $3.99 (even at the Lego store) with a person and a small car or something. At DTD you can have him pick out a small set while with DH.
Here are some of the 3.99 sets

I think they are more than worth the money as they are easy for my guys to put together themselves (ages 5 and 6).
I was able to find the 'people' in the minipacks for $1.99 at Five below and I think for $2.49 at TRU.
I also joined the VIP club today, which is free to join and you get points on how much you spend, either online, or in the store.
*************Does anyone know if you can use Disney GC in the DTD Lego store? We have a ton of GC and I would love to get the kids a decent set!*****************
