It's a 4.5 hour drive....depending on your speed. Carretera 307 is a good highway and you should have no problems, but be cautious of the...topes de velocidad...(speed bumps)especially when driving at night. Also, make sure you have your rental car papers in order....in case you are stopped. Have driven this route over 12 times, before i finally moved to Belize. Never had a problem.
