We will be staying in San Ignacio for 7 nights and have rented a 4 wheel drive vehicle. I know that some of the tours (Tikai) will require us to take a bus tour but since we have our own vehicle can we do the following tours ourself (meaning drive to the location and get a quide a the site or do our own self-guided tour). We are interested in Barton Creek canoe adventure, Caves Branch Cave tubing, Xunantunich tour, Crystal Caves and ATM. I realize that we must have a guide for ATV tour but can we drive to the site and get a guide there or do we have to take a bus ride with a tour company. Since we are paying for a rental car for 7 days we would like to use it as much as we can. Anything else that we should add to our list during our 6 days there?
