The branch of Mens Wearhouse that delivers to Disney resorts is the one in Winter Gardenthe other one in Orlando won't do it:
14748 West Colonial Drive
Winter Garden, FL 34787
(407) 656-7700
The way it works is that each fellow gets fitted at his local MWTux, and then they send the measurements to the Winter Garden store. When everyone gets into Orlando, you schedule a time to have the Winter Garden store deliver the tuxes when everyone can try them on. Then they make any alterations necessary and bring back the tuxes closer to the wedding.
Carolyn Allen - (407) 238-2722 - also provides this service, without the pre-arrival coordination supplied by MW Tux. The fellows would need to get measured on their own (some local tux shops will do it free, but they may be grumpy when they find out the guys aren't actually renting there) and give you their measurements. Then you would give their measurements to Carolyn Allen. The rest of the process is the same.
