havnt been to thailand with littlies, but we went to patong, chang mai and bangkok.
HATED bangkok with a passion, we stayed in the china town end and it was horrid! and the ppl on the streets were the biggest scammers ever, never had an issue in other places.
Chang mai was lovely, its a city, alot smaller than bangkok, but very quiet and pleasant and TBh i found the shopping better there than bangkok, everyone told us that bangkok was the best for shopping, now i wish i had of bought everything at chang mai.
patong...tourist central but lots of fun anyway.
Have an awesome trip!
