Kissimmee is far less "bucket n spade" than International Drive...so many English Bars u cud be in Blackpool , but with better weather!( not that there is anything wrong with Blckpool!!)
U may find a villa a better option, but wud recommend car hire...Alamo usually the cheapest. That way, you can do the parks and sights then relax around your own pool without hundreds of screaming saucepans, overought with too much Disney!! Skinny dippin in the pool at midnight, whilst yamming ya way thru a veery large bucket of ice cream! MMMmm!!
