The Wat Pho temple in Bangkok is a site you don't want to miss. This is particularly true if you're not going to be getting out of the city. This is a group of temples that's truly what you would expect from Thai temples. It's a large complex of buildings each with a unique temple or temple use inside. The most famous temple of this complex houses the reclining Buddha. It's also the most crowded of these temples, but well worth waiting for. The rest of the temples are all very pretty, but you can decide if you want to explore them by poking your head into the door and making an assessment.
The best part about Wat Pho is the fact that you can wander. There are all kinds of little passageways and gardens well worth checking out. As well as the temples, there are also schools, various shops, and even a massage place. Not all of the buildings are open to the public, but we had no problem walking around the complex without being stopped.
The most difficult time you'll have is getting to these temples, particularly if you're staying in the new part of city. The Wat Pho temple is located in the old city, and is not serviced by the sky trains. This means you have two choices to get yourself there, taxi/tuktuk, or boat. If you take the boat you'll not only get to the temples, but the view along the river is spectacular. There is a Sky train that will drop you off right at the boat dock where you can get your tickets for the boat that will drop you off right outside the temple.
