Hey I just saw this thread and noticed you last visited Tikal. I was wondering if you thought about visiting the tiny town Uaxactun north from Tikal. In 2007 I went up there and even further North to Dos Lagunas which is on boarder with Mexico. Very cool. I assume you are done with Tikal now and hopefully you decide to check out the Semuc Champey. It's a beautiful area with a really cool hostel scene. The main feature is a river that goes underground for a 1/4 or so with pool and drop on top. Hard to explain, google pics will show you how cool it is. Definitely worth it to check out.
