If you like your attractions a little left of centre then consider the below options that i read about in The Daily Telegraph's pull out travel section "Escape".
In Cottonwood, Idaho The Dog Bark Park Inn
Dog Bark Park Inn offers rooms for the night for 4 people comfortably located in the belly of a 4 metre tall beagle nicknamed "Sweet Willy."
Perhaps more mainstream yet still quite "different" is the 80 year old Delta King Riverboat
Delta King now permanently moored on the river at old town Sacramento, California.
In San Luis Obispo - The Madonna Inn
Madonna Inn displays its multiple personalities with not a handful but 109 rooms each one meticulously decorated to suit a theme. Here you can play at being a caveman or Napoleon, take on the persona of a hillbilly or a conquistador or simply go ape in the jungle room.
Hawaii's Volcano Hotel
Volcano Hotel should provide the necessary adrenalin rush. What if Mt Kilauea one of the World's most active volcanoes, grumbling away nearby blows its top tonight?
Train buffs should check out the beautifully recreated Aurora Express in Alaska
Aurora Express where they sleep in restored railway carriages called Immaculate Conception, Can Can or Gold Mine, then wake up to the same stunning view.
An unusal option The Pigeon Point Lighthouse keepers quarters
Pigeon Point Lighthouse on the central coast of California
In West Virginia there's the annual Road Kill Cook Off
Road Kill Cook OffDoes a Garlic Festival tickle your fancy

Gilroy Garlic Festival at such events you can find such scrumptious dishes as garlic ice cream? garlic jelly?
More weird is Minnesota's Spam Museum
Spam Museum which is filled with Spam - obilia erm....ok
Try Opaque
Dark Dining Diners at the 3 west coast (L.A, San Francisco and San Diego) dont get to see their food at all because they are served in total darkness (this one actually sounds interesting to me).
A mammoth Tug-o-War appeal to you
TugFest each August across the largest river in the USA the Mississippi, ten 20 member teams compete in hefting a 730 metre, 308kg rope which is stretched between Illinois and Iowa.
