i think its just a case of they get booked into wherever they can be accomodated. i've seen all the kids in the calella palace, oasis park, olympic, etc
i would not think that any hotel would be exempt from the little angels, but think that the sant jordi may not be a natural choice for them.
i would avoid any hotel in the htop or serhs chains and you will probably be ok.
best i can do

many thanks for the reply relatives of ours went to malgrat a week later than normal in may not realising that the tournaments would be played.we normally go in may and september and are trying to avoid clashing with the tournaments if we can for next year.
many thanks
