Yes.
Your OP is a little ambiguous, but I'm assuming you're talking about from your resort to the rope drop -- NOT from the airport to rope drop. Right?
For six, you need to order an Uber XL. One XL will be less expensive than two X's in Orlando.
An XL will transport 6 people without luggage, coolers, multiple strollers, etc. If you're taking a lot of STUFF in addition to six people, you might need an XL and an X.
