They've got a nice one in Zona Rosa area of San Salvador, not far from the Hilton Princess. I took a look at it, they give a better rate ON THE WEEKEND believe it or not. (Probably because lots of business people.) El Salvador has a pretty good economy going on right now, the best in Central America in growth according to a financial newspaper I was reading down there. The Radisson has an airline rate right now as 116 PN dollars on the weekend versus 135 per night on the week day. Upgraded suite was quoted at being 145 dollars on the weekend. Very nice looking place indeed.
Personally I like the INTERCONTINENTAL hotel. I like the location, more luxury than I need.
