Assuming I could completely slather myself with sunblock (and wear sunglasses), I'd pick the first one! I'd enjoy it B)

I would be worried about being in the sun all day. I can't dance that long. Well, I can't really dance at all, but I did almost pick that option. So I'd go with the walk as long as it was somewhere I would never end up living, or a big enough city.

beach...I like the idea of being paid a million dollars to just lay there and nap in the warm sun.

I would do any of them but the 1hour would be the quickest way to get the million lol!

I'd walk around the city naked. Mostly because I'm a lazy bum and 6 hours sounds like a lot of work, hahahaha. None of these disturb me.

My problem with the first one is I'm pale and burn easily. So I would litteraly look like a tomato. Plus it'd be too many people.
