FantasiaBish,
Listen to all of them.... they are right!
Let´s not exagerate though... good service could be anywhere, at any hotel, doesn´t have to be a Disney one... BUT, the main difference, at least for me, would be the huge advantage of transportation. If you are not familiar with the streets, driving in Orlando is a hazzle. Full of tourists who don´t know their way around... go figure! hehehe...

Besides, what if part of the group wants to take a nap, or go to another show, etc.? You can do it without moving the whole group´s schedule and meet later somewhere else. Easy. Btw, you can consider a pair of radios... hehe
I would suggest you to stay on site and rent a car only for the days you want to get out of property and enjoy the rest of Orlando! Do not miss going to International Drive! hehe.. psst psst.. "Bahama Breeze".. :slurp:
The All Star are the cheapest option. Check for deals at
www.mousesavers.com Many people have post here that they found great rates there. Good Luck!
In case the majority goes for the other option, let me suggest you to stay around SR.535, or Hotel Plaza Blvd. which in my opinion are the closest ones to Downtown Disney and the parks.
