Bangkok Itinerary

I put these ideas together for someone who had already done a lot of cool things in BKK.  He was just going to be in the Thai capital for another stretch.

Day 1

Chinatown  - There's a temple with a solid gold Buddha at entrance to Chinatown: Wat Traimit.  Closes at 5 PM.  Chinatown gets going 6 PM and after.  If you want to enjoy some bars in Chinatown, Teens of Thailand and Asia Today are very popular.

After Chinatown: Soi Cowboy.

Day 2

Wat Arun - opens at 8 AM
Grand Palace - opens at 8:30
(Make sure to also go inside Wat Phra Kaew on the Grand Palace.  Contains the Emerald Buddha).
Wat Pho (Reclining Buddha) - opens at 8 AM

I would for sure carry a full water bottle and wear sun screen and hat.

Evening: Nana Plaza and Thermae.

Day 3

Terminal 21 for souvenirs and food court for dinner, followed by a massage on Soi 23 and maybe a last stop at Soi Cowboy.

Day 4

MBK shopping

Belga Rooftop Bar (best by 6 PM) - between Asoke and Nana BTS stations.

Kiss Massage after Belga.

Day 5

Mahanakhon Sky Walk - take BTS there.  Best to arrive by 5:30, get ticket, then get to top. Leave hotel no later than 5 pm, possibly 4:45). Stay till sunset (6:45 pm).  Wear sun hat.  Best 360 views of Bangkok.
