Prices are not that far off what you will feel is the currency exchange rate! Another thing is that there is a 150 baht surcharge for every ATM withdrawal, so take out the maximum you can to cut down on lots of ATM fees for cheap amounts. Cashing a travelers check is still only 33 baht. It you get them for free from your bank or credit union they look a little better now - only bring the largest sizes you can get.

Here are a couple old links on prices:

The price will be what it is when you arrive, nothing we can do about it! Some cheap hotels didn't raise their prices that much. You might be surprised that many things are still at the same or close to what you paid years ago.

Good luck.

One commodity that seems to have really gone up in price the past 5 years or so is beach accommodation down south. That's partially because the standard has gone "up" as wooden huts get replaced with glass&aircon units, but also just owners/developers realising how much they can get away with charging to the largely European family/couple type market who consider anything under 3000 baht on a beach to be a bargain. Cheap bungalows I stayed in for around 250-500 on Ko Phangan and Ko Lanta are pretty much double now and more in high season. It's increasingly common on the more popular beaches to find prices upwards of 3000-5000+ for a modern legoland block.

What the others said about the change in exchange rate will also be felt by many returning visitors (especially British, GBP=75baht July'05, now GBP=49baht)
