Day 1 (Guangzhou Baiyun Airport ~ Suvarnabhumi Airport)
The flight arrived at midnight, we called the hotel (Suvarnabhumi Phoenix Hotel) for airport transfer service. The transfer service seems to depart on the hour. After calling the hotel, we waited inside Gate 4. The hotel was average (Thai hotels generally don't provide slippers), but it was okay as a transit hotel, the service was good. The smallest banknote for tipping was 20 baht, equivalent to about 5 RMB.
First, we applied for the visa on arrival, then entered Thailand to collect luggage, and went through customs.
Left side for fast track, right side for visa-free entry, review, got number 168, walked straight to the waiting area, don't tip customs officers.
Grand Palace, Bangkok
Day 2 (Airport Hotel ~ Pattaya)
The airport hotel took us back to the airport, we took a bus from the far left of the first floor to Pattaya (130 baht), got off at the first stop, then took a taxi to the Pattaya hotel.
We booked the Felix Hotel in Pattaya (near Tiffany's Show, roughly near Airport 21). The hotel environment was quite good, also didn't provide slippers. Taxis booked through the hotel were cheaper than Grab.
We only planned to spend one day in Pattaya, since we didn't want to go to the beach, so in the afternoon we went to Pattaya Floating Market. Not recommended, but you can take a look, just buy the entrance ticket, don't buy the boat ride. Things inside are not cheap at all, you can try the coconut durian ice cream. Round trip was by hotel-arranged taxi.
In the evening, we went to see the ladyboy show, highly recommended, worth watching.
Tiffany's Show
Day 3 (Pattaya ~ Bangkok)
Took a taxi to Pattaya North Station (the nearest station), from Pattaya Bus Station to Bangkok shopping district, Ekkamai, 119 baht, large luggage costs extra 20 baht. Navigated to take BTS, then a few stops to near the hotel (had to cross an overpass). Our Bangkok hotel was Victory Executive Residence (200 meters from the duty-free shop). In Bangkok, it's better to stay near shopping districts.
In the evening, went to King Power Duty Free to eat (200 baht food voucher available daily), looked around and found only L'Oreal was cheap, others weren't cheap.
Day 4 (Bangkok)
Took BTS to Chao Phraya River, queued for Wat Arun (N8), then to Grand Palace (N9). From Wat Arun, turn left and keep walking, there are 4 baht boats to the Grand Palace, don't take tourist boats (60 baht). After getting off the boat, it's recommended to take a vehicle to the Grand Palace. We walked at noon and were dehydrated by the time we reached the Grand Palace. On the way, we passed either Wat Phra Kaew or Wat Pho, but we were too tired and went directly to the Grand Palace. The Grand Palace was average, you can take a quick look. It's recommended to go around 3 PM when there are fewer tourists. Around 4-5 PM, you can take a tuk-tuk to Khao San Road (it's too hard to find taxis near the Grand Palace, tuk-tuks can be bargained, about 120 baht).
At the beginning of Khao San Road, there's a good massage shop, first floor for soliciting customers, second floor for massage (200 baht, can bargain). Khao San Road has lots of food, prices are reasonable and not expensive.
In the evening, we went back to the duty-free shop for dinner.
Day 5 (No plan)
Took the subway to Pratunam Market, which is a clothing wholesale market, not recommended.
Coincidentally, Erawan Shrine was nearby, so we walked over to pay respects.
Believed online rumors that with Grand Palace tickets you could visit the old parliament building, but it was fake, not open. Then we took a taxi back to the shopping district, went to Big C to buy golden pillow durian, mangosteen, and various instant noodles and snacks. Tao Kae Noi seaweed wasn't cheap (golden pillow durian wasn't cheap, mangosteen was very cheap). At CentralWorld bought Musang King durian (expensive, but very delicious).
In the evening, we went back to King Power Duty Free for dinner (good to live nearby, can get free meals, food near the duty-free shop is good).
Day 6 Return trip
The duty-free shop has free shuttle buses to the airport, need to show shopping receipts to book seats in advance. The earliest bus is at 12 PM, takes less than half an hour without traffic, heard it takes about an hour with traffic.
Flight at 3 PM, need to depart three hours early (many procedures). Security check was fast, boarding was slow, collecting purchased goods was fast.
Drank a terrible-tasting beverage on the plane.

Thai people are really friendly, language doesn't hinder our connection. Didn't do much sightseeing, ate a lot. Air conditioning is very strong everywhere, best to bring a light jacket. It gets very sunny at noon outside, otherwise this time period is quite good. The hotels I booked all had swimming pools (many hotels here have pools), but we didn't go swimming.
