travel suggestions needed

[vfb2girls]

We are planning on splitting vacation to 5 days at a Disney resort and 5 days at a Universal resort. We do not want to rent a car. So with that we are planning on using ME for the one way trip from the airport to our resort but I am wondering what would be the better way of traveling to our Universal hotel, can we hire a towncar to pick us up at our Disney resort and take us to Universal and then pick us up to take us back to the airport or would it make more sense just to use a taxi service? I am not sure what the price difference would be between a towncar service and a taxi service. I thought about just using the towncar service to pick us up at the airport and drop us off at our Disney resort and then picking us up at our Universal resort and taking us back to the airport but do they do that? And how expensive would that be? I am really getting stressed about this transportation thing so any suggestions would be greatly appreciated. Thank you
