Hi Hils,
There are two people who are booked in single rooms, however, we cannot guarantee that they are actually travelling by themselves.
In regards to the Christmas and New Year trips, we do not have any more planned for 2015 - but you can of course combine a Christmas holiday and a New Year holiday, which in effect gives you that combined festive break.
Just keep your eyes peeled for 2016 departures.
Kindest regards,
Monty
