Yes. There are canal boats in Bangkok.
There are many floating markets in Bangkok, as well. They are very fun. Hope you're having fun there! The best places I've been to in Thailand are: 1. Pattaya - Jomtien Hotel which is right off the beach and only 45 bucks a night. Very clean. Two outdoor pools. Gym. Spa. Free Continental Breakfast. Everything!

And emerald pool/crystal lagoon in Krabi... But there is a bit of hiking, so you need good walking shoes. No young kids would be best.

The worst place was Koh Lanta (it's a little island, total waste of money but thats just my opinion). They say its really good but it just doesnt match up to the hype.
