If it's a hot day, most of the locals will go to the water park when it opens (usually 11:00am). I have never waited more than 1/2 hour for Raven or Legend and it is often a walk-on.
HW has a nice selection of flat rides for a park of its size - tilt-a-whirl, round-up, falling star, octopus, flyers, etc.
I have found the food to be better than most themers and CHEAPER.
IMO, HW is the best bargain in any amusement park - free drinks, free parking, reasonable admission (1/2 off for ACE members), and a nice water park (w/free tube rentals) is included with admission. Enjoy
