Northern Thailand at $12 a nite

Our visas run out end of February and we need to go to Chiang Mai to get a new one. We also have some other business there, so we'll spend about 13 days in the Lanna Kingdom, (Chiang Mai, as it used to be called.) We are looking at condotels, some as low as $100 a month, that are what they sound like, a cross between a hotel room and a condo. The lowest ones aren't so wonderful, but they rent for either $12 a day or $100 a month, can't beat the price! They have higher-priced ones; really there is something for every budget. We will look for something clean and quiet. Breakfast included would be nice. There is one beautiful place that is running a special for $20 a night including breakfast if you stay a week. Breakfast and a bed for the kids would make it $30 a night. Living here so long makes it hard to want to pay the extra $10 a night. I think we will bring a mattress & sheets for the kids and some extra croissants and yogurt in the morning for the kids. They might give us funny looks, but that's alright!
