Oh, and I almost forgot, there's another place on the planet to go where there isn't any snakes.

Ireland.

They speak English, it gets cold, but the weather is fairly nice for a good part of the year, and there's a lot of fun touristy things to do.

edit

and after a little more googling (because even though I knew Ireland didn't have snakes, I thought it couldn't be the only one) I found the other places that don't have snakes. New Zealand, Hawaii, Greenland, Iceland, and the aforementioned Antarctica.

If it were me, I'd go to either New Zealand, or Ireland, or Hawaii. I wouldn't need a passport for Hawaii, but New Zealand actually sounds a lot more fun. Ireland would be cool because I'd be able to do a lot of genealogy research at the source.
