Room sizes at Le Totem, Flaine?

My wife and I and our 20-month old daughter are staying in the Club Hotel Le
Totem in Flaine later this month. For a number of reasons, we are booked
into one of the basic rooms (type A in the Crystal brochure - north facing
twins), but Crystal have now told us that there is not enough room for an
extra cot/bed in the room. It seems a bit strange that they took the booking
if that was the case - is anyone familiar enough with the rooms to give us
an opinion?

I just wish we could be there this week!

Thanks, Chris
