I second Hyatt Regency Grand Cypress if you are looking for a hotel rather than a home/townhome/condo. We stayed there in 2014. Ask for higher floor room, pool view. We saw fireworks from more than one park, our kids loved the pool (we normally stay at the Polynesian, and I think my kids liked this one even more, no lazy river, but they do have caves to swim through....not heated in that section of the pool and it never gets sun due to caves so be aware. We traveled in early September, and it was fine to swim in.). Drawback for us.....full size beds rather than queen if I recall correctly.
It was like being on property.....short drive! GPS took us through back route that I think Cast Members take.....easy access to WDW parks.
Be aware of resort fee b/c they offer tons of activities.....resort fee is not optional even if you skip all the activities.
They have buy 4 nights get 5th free summer deal, and they offered that 2 years ago so must be a standard offer.....that gets you into good price range.
Good luck!
