My husband and I traveled into Tikal from San Ignacio with another couple on a day trip in June, 2000. We knew about the security issues, but decided to go anyway. Our guide and driver were Guatmalan; we thought they would "know the ropes" as far as security, and they came highly recommended to us. We are REALLY glad we went; it was one of the highlights of my life to stand on top of some of those Mayan temples...I kid you not, it was really breathtaking. I urge folks to go if they have an adventurous spirit, and pick your tour companies carefully...shop around and do some research.
