Getting from Disneyworld Florida to Universal parks. Easy when not driving? Cheap?

Since you say you do not drive, I guess renting a car isn't an option. There is always a cab, or also there are a couple of car services that I have always seen highly recommended on various travel sites. One is called Quicksilver (www.quicksilver-tours.com), and one is Happy Limo (www.happylimo.com). They are supposed to be good and have various different size cars/vans/limos to suit your needs and size of your party. I would check out their rates, and you might also try calling them and ask if they will give you a deal if you travel with them several days in a row.
