While visiting Thailand, we wanted to build in a day trip to Ayutthaya and Bang Pa-In Summer Palace. I found the easiest way to do this was to book a private tour from Bangkok to Ayutthaya and Bang Pa-In Summer Palace. I highly recommend booking private tours for any trips in Thailand that require driving a long distance or to places outside the reach of public transportation. Private tours are not that expensive considering the price includes both a driver and a tour guide. We had fabulous guides and learned a lot about the places we visited as well as the country and culture.
