My daughters are age 6 and 9. We have gone on many trips to WDW. my 9 year old loves rides like thunder mountain, everest, and dinosaur. we haven't convinced her to try rocking roller coaster or tower or terror yet. My 6 year old hates all of these rides; she sticks to winnie the pooh, buzz light year space ranger spin, and small world. My question is, will a couple days at universal be worth it for us? How many rides or other attractions would there be for my 6 year old to go on? TIA
