We will be in Guatemala for just over two weeks in February 2013 and would like to see Tikal. We are all experienced travellers but it is the first time to Guatemala for any of us. With five of us the flights add too much to the cost. I know there are overnight buses, but with five people is hiring a car and driver a viable option? Also, are the overnight buses safe, seems there have been some comments that these buses are the target for robbers. Thankful for any advice.
