Yeah thats pretty cheap. I would say it's at least double here. Hmm Brazil would be interesting maybe. Only thing is I have heard many reports about you really need to stay in the tourist areas or you can easily get into trouble and I'm one who likes to roam around where I shouldn't.
My HAW would get upset with me because when in the Philippines I liked to go out most every night and just walk around the streets for an hour or two after dark and I definitely went places most people wouldn't. Even my Filipino friend and his wife thought I was a little crazy for some of the places I would go by myself. lol
I use to do the same thing in Mexico. I would get way off the beaten path and just walk for hours through the back streets. I'm not to sure I would do that in Mexico anymore though.
If you get it done make sure to let us know and take pictures before and after of course. If it all works out I may have to plan a trip and come visit you for a week or so. lol
