Derpelican..........just checked the terms and conditions and it states........use on minimum 2 night weekend stay(fri/sat or sat/sun) apart from Middle east where maybe defined as thurs/fri/sat.
I am getting more confused by the minute........UK1's answer seems right if you view the wording on back of my cert.
So do I book Sat/Sun .........then have to make another booking for the Mon/Tues
