I'm heading to Europe this summer, and we will be travelling with our adult child who needs to stay in our room.

I have lots of points with all the major hotels, but unlike the USA where pretty much all rooms fit 4, Europe doesn't even seem to fit three. It wasn't an issue when our child was little, but is probably now.

Unfortunately, when I put three adults in the search, the price jumps exponentially...it costs more than two rooms in most places.

Any advice on particular properties that may be more accomodating, or any tips. Just showing up with the three of us seems like a really bad idea!

Thanks.
