HI, I have heard alot of good recommendations about D J Scooter. He does have a website but I don't know it off hand. Disney contracts him as well to do thier weddings. I had requested him based on everyones reviews even though Disney won't garrantee they will get him. I actually contacted him myself in advance and he penciled me in and I told Disney this as well. I just found out yesterday Disney booked him for our wedding.
DJ Scooter and DJ charles miles both seem to come highly recommended as well as Chuck Johson...they each have different styles so it depends what you are looking for I guess.
Excellent! You'll have a great time! He had us all (including my 74 year old nan) doing the conga round the convention centre! It was such a good laugh!
