Go to Sukhumvit soi 33 (soi is a small side street) Go to Dream Heaven (checkout their website) as you will see price includes full service. Also see SKV33 and Hera masdage also There are many full service shops in this one soi to keep you busy for a few weeks. Just ask when you go into a shop as most do full service. Also they will bring the girls out for you to look at and choose.
