ORLANDO, Fla. — They don’t call it miniature golf anymore. The term nowadays is adventure golf, as in Hawaiian Rumble Adventure Golf, Pirate’s Cove Adventure Golf. They’re part of the other Orlando, the under-the-radar part that exists outside the Disney-Universal-SeaWorld triumvirate and, with two notable exceptions, thrives mostly along a 4-mile stretch of International Drive, I-Drive for short.

I-Drive is a dizzying, often overwhelming compression of businesses that live for the tourist trade. The list goes something like this: 226 places to eat, 102 hotels and motels, 41 movie screens not counting those at Universal’s CityWalk, 18 car rental offices, eight gas stations, seven supermarkets, six night clubs, five Walgreens, four 7-Elevens, an unknown quantity of vacant lots and an ever-shifting number of Bargain World souvenir outlets.

That’s not the whole list. That’s just the backdrop for things like Fun Spot Action Park, Skull Kingdom and Sports Dominator — all establishments that leave you wondering exactly what goes on inside. This is also the place to lie on a bed of nails (WonderWorks), skydive without a chute (Sky Venture Orlando Indoor Skydiving) or see a deck chair salvaged from a famous shipwreck (Titanic — The Experience). You can even play mini — no — adventure golf.

Most of the activities on I-Drive are self-explanatory. Wet `n’ Wild is a water park. The mini-golf parks offer exactly that. Fun Spot Action Park and Magical Midway deliver go-kart tracks, arcades and carnival-like rides. Air Florida Helicopter Charters takes you on flights of varying lengths.

But some attractions need a little more explaining. Skull Kingdom gives haunted-house tours by day and dinner magic shows by night. Sky Venture Orlando Indoor Skydiving puts you in a flight suit and helmet, instructs you on wind-tunnel dynamics, then takes you soaring in its vertical shaft.

Ripley’s Believe It or Not! is a museum of the weird that exhibits oddities from around the world. WonderWorks is a sort of hands-on science lab, where you can experience mild hurricane-force winds, see what a 5.3 earthquake feels like, leave your shadow behind (something about the light-absorption properties of the special wall they use for this), design and ride a virtual roller coaster, see what you’ll look like 10 years from now or what you’d look like if you were from another race. Before you leave you can play a drum accompaniment to your favorite rock tunes.

At Titanic — The Experience, you’re assigned the name of a real passenger from the fated vessel before a guide in period costume leads you to re-creations of a First-Class cabin’s sitting room and the Grand Staircase. Along the way you’ll see historic artifacts such as an actual deck chair that was salvaged the night of the disaster, touch an ice wall to see what an iceberg might feel like and walk along an “exterior deck” where the temperature is cold but not nearly as low as the night of the sinking. At the end, you learn whether you, or rather the passenger name assigned to you, survived.
