I would check the room types you are being booked into as well when deciding if this is a fair price. I have stayed at the Delta Whistler and there are 3 room sizes - a twin room with a very small kitchenette area, a 1 bedroom suite which has a bedroom with a separate living / dining / kitchen room, or they combine the 2 to make a spacious 2 bedroom apartment.
With a 16yr old daughter you want at least the 1 bed suite. Our daughter was 11 when we went and we upgraded to the 2 bed suite when we saw the size of the 1 bed suite on check in.
If you're in large suite accommodation the overall price may be justified
