It's no exaggeration to say that this is a must-do if you're going to Pattaya. This time, I only booked a one-way trip from Bangkok to Pattaya and returned by bus. The itinerary was: 7 AM pickup -> Pink Ganesha -> Tiger Topia Sriracha Zoo -> Lunch -> Sanctuary of Truth -> Wat Khao Chee Chan -> North Pattaya Bus Terminal. After that, I bought a bus ticket, went to the Night Bazaar, and returned to Ekkamai by bus. A point to note about this itinerary is that when going to Pink Ganesha, since it's not in Pattaya, you have to pay the driver an extra 1000 baht in cash. Pink Ganesha doesn't have an entrance fee, so it's not a big concern, but those going should be aware. The driver was very kind, confirming directions and whether tickets were needed and properly booked even after arriving at each tourist spot.
