Don't let the good location to parks fool you.
Extremely disappointed with this property. The pool grounds are nice, but the rest is old and nasty. Small number of the staff try really hard, but they are the exception. I am a Hilton Gold member and loyal for many years. I used points for this stay and felt cheated. Seriously considering taking my future travel elsewhere. Below is a list of items my family and I experienced. If I knew to expect these, I would have chosen Florida. 
Expect your room not to be ready on check in. (5:30 in stead of advertised 4pm)
Expect to be sent to voicemail when calling for services from your room(48 hr response times)
Expect your room service tray to sit in your hallway for days.
Expect to call maintenance at least once a day for something not working (toilet would not stop rumming, bathtub would not drain, cordless phone never worked.)
Expect smokers in the rooms below rooms 521 and 523 which prevents you from using the balcony in any way.
Expect to pay an excessive amount for parking.
Expect to pay cash for the yellow cabs contracted to the hotel (even though there are stickers in the window showing credit card logos.)
Expect unannounced tree maintenance at the pool the day you decide to stay on the property.
Yes, this property is close to sea world. But my advice is to stay clear of this Hilton. It is not what you think a 4 star property should be. Sea World has lots of parking and shuttles from the other hotels.
