Hanno, That's great. They arrive in Amsterdam on the 29th and go directly to Texel where they will stay the night prior to starting their course. They finish on the 6th or 7 and they may only need the beds for 1 or 2 nights then. They return to Canada on the 8th. At 18 he will be anxious to try to go through as many of your beers, and your women, as he can.
PS, did you receive the books yet?
