No, if you have been there several times they will pay for taxi return, however it is easy enough to get a taxi at the airport to the Sawaddi for 800 baht, clean safe and reliable so about 20 uk pounds well worth it.
You can arrange with the hotel at an extra cost. it is definitely easier than taking public transport and cheaper than a private taxi at the airport.
Airport transfers were included in ours but each company works differently. So check with whom you booked through.
I don't know. My tour operator did everything.
I have done it everyday last year our taxi let is down didn't turn up so for 850baht I used the safe option and got the hotel to book me one and I would not do it another way now....
