Just returned from Calis and used Rain Transfers for both legs of the journey to/from Dalaman airport.
On arrival at Dalaman, we found the desk for "Rain Transfers", produced our email confirmation and we were directed to a car that took me and the better half straight to our apartment in Calis. We were the only passengers on that flight going to Calis so we had a car all to ourselves.
We had to reconfirm the pick up time for our return the day before our departure. The pick up time had only altered by 10 minutes from the time I was given at the time of booking so that was no big deal.
The driver arrived smack on time (the ammended time) to take us back to the airport, this time we did share the mini bus with 2 other couples but as we were the last to be picked up from Calis, it was then straight to the airport.
I was very impressed with the level of service given, very good communication, very polite drivers, very punctual and at an extremely good price (£26 return for the 2 of us!!)
Can't complain at that lol
I will be using them again in the future and would recommend them.
