i went to the Arum lasy June and we had a double and a single bed in our room, Nice hotel i have to say...
Air-conditioning was a bit rubbish as during the night they switch it off and only the fans are running so you wake up hot.
the drinks are pricey so dont go overboard, we used to forget to settle our bill every few days and get hit by a huge bill. the cheapest bottle of wine in the hotel was something like £13
