Thirded.
We went last week, and while we had a good time -- when the sun came out, there was not nearly enough protection anywhere. Granted, there's Slippery When Wet, and Reggae River Falls, but they're only worth a few moments of cooling ability. (plus you are assaulted by children)
Zep really does have a bit of a rattle to it, but it's still a good ride. I'd rather be on Patriot any day of the week, though. Nights in White Satin is surprisingly good. I expected it to be fairly dull but it was *really* trippy and quite a visual delight if you like that sort of thing. Maximum RPM loads FOREVER but the Karaoke Queue is worth a chuckle (and the hostesses are hot).
Food is pretty good, too, although service is exceedingly slow. Props to them for not serving just the basics! (I had a Black & Blue Burger, My Mom and Wife had really good Fish & Chips, and another in our party had a Prime Rib Sandwich.)
They have dropped the daily price to $45 -- not a good sign for the park's stamina -- and while it's still more than some parks, it's a BARGAIN for a Myrtle Beach attraction.
Also note if you would be going with kids who are too old for kiddie rides but not yet 48", they're gonna be real bored. They can't ride even Slippery When Wet, which is extremely tame.
I would *NOT* ever take a trip just to go there -- but if you're IN MB for any other reason, it's **definitely** worth going.
