Kaew Samui Resort, Surat Thani
Is located on the 401 ring road that leads around the city and is a good choice if you're 'stuck' in Surat Thani on your way to the islands or on your way to Bangkok coming from the South. Shopping malls are nearby, the city is nearby and the ferries in Donsak to Koh Samui and the other islands are just under an hour away. The hotel (it's really not a resort!) is located in an industrial area though and is mainly catering to Thai business people.
The restaurant is nice and free wifi is available, ask at check in and it's a newly build hotel.
Low prices are a plus, it's convenient and just what you need for a night's stay in Surat!
