What to do with these 2 domains...

[Lion]

I bought 2 domains a couple of months ago thinking they were a sure sell at sedo.com (AmazingHotSpots.com and FabulousHotSpots.com), but I havent really received any offers. The sites are just sitting there parked with Sedo. I was wondering if anybody thinks it'd be a better idea if I ran with them and developed them into something useful like a travel destination site or nightclub search, or maybe turn them into adware sites (which I'd hate to do but heard the money is good)?

I'd really appreciate any advice.
Thanks
