We have 8 nights booked at VWL in about 12 days. it's in two ressies, the first is 7 nights and the 2nd ressie is 1 night. I was told the two ressies are linked so we wont have to change rooms and they will see that at check in. So here's my question, if I do online check in for the first ressie do i need to go back on and check in for the 2nd one?
