This is a really interesting tour to north of Bangkok to Ayutthaya where you visit around 4 temple sites! Recommended for sure and a must if you are in Bangkok! There weren't many tourists at all and this made the sites that much extra special. Amazing pictures and feel of history walking around. The guide is a nice guy and will have a 10 minute chat at every location, whereafter you can explore yourself. We actually finished the tour at 13:10, so around 15:00 we were back at the hotel. It was getting hot around 12:00 so finishing (early?) around 13:10 was perfect id say. If the pickup point in Bangkok is not that convenient, you can opt to get a 800-900 baht taxi at 7:40 and go to the meeting point in Ayutthaya, around 8:55 arrival. Then ask the taxi driver to bring you back for the same rate or see if there is place in the minibus from GYG. We had a miscommuncation with the guide at the start of the tour but it was solved and as said the tour was great so still above 4,5 star:)
