The Klook day tours I've joined so far have never disappointed. This time, our tour guide Thana was extremely attentive, preparing water and small snacks for every member. During the bus ride, he also explained Thai culture and the main buildings we passed along the way. Although lunch was not included in the tour price, the guide reserved a restaurant for us in advance (saving everyone the time of searching everywhere for seats in a crowded tourist spot). Despite unfortunately running into all-day heavy rain, the guide still professionally led us through the entire itinerary and did his best to take great photos for everyone despite the weather. If you want to experience wearing traditional Thai attire, the guide can also help arrange it (at your own expense). Quick tips: 1. There is a dress code for entering the Grand Palace—short skirts, shorts, ripped jeans, etc., are not allowed, so you will need to buy a pair of pants or a skirt outside (around 200 Thai Baht). 2. You need to take off your shoes to enter both the Grand Palace and Wat Pho, so it is recommended to wear shoes that are easy to slip on and off (rain makes things a bit tougher, so bringing an extra pair of socks to change into is advised).
