we did a
transfer with
ICR a couple of years ago,instead of teh first choice transfer,which the year previously had taken 3 and half hours.
we had no problem and were there in less than 1.5 hours.the only down side is you have paid for a transfer with your tour operator.
THE solution is book everythiong yourself ,we have done that now 3 times with john at ICR selecting the apartments,transfer and then our own flights.much better value and well organised.
