Detour:
I too was in your camp, Being Board of Ed member and score our convention was in Orlando Center, fortunately I was housed at Universals Portofino! Score! I had to pay for airfare and tickets to Universal for family but vendors paid for mine including private evenings in the parks after they closed for family and me. I was in the center by day but my family had a blast, no buses only boat launches 5 minutes to the parks and City. Some rides were too advanced but there was so much for them to do in the parks and unlike attractions of Disney. Zip Line just for kids, example. Their Dr. Seuss area was inviting for younger children too, much better than Fantasyland. My family packed in 5 days of fun between two parks and never bored. Then we went onto Disney for 7 days when my convention was over for my vacation. I had never considered after decades of loyal Disney touring ever leaving the property. If it wasn't for the convention I wonder if I ever would have. Now we start family trips at Universal, staying in the Portofino and jump ship to Disney for our Magic. The CM child often jumps over to Universal, not better, not worse, just variety.
