I’m a family of 5 smallest one 4 would sleep in the parents. Is it possible to book a quad room for this?
I am sorry but I do not have this knowledge. As others have suggested, email the Hotel group on their website.
They do have family rooms but not sure how many they can accommodate. I would email the Imperial Hotel Group and ask.
The rooms we have stayed in have been quite small but they may have family rooms. It is possible to email the hotel to make enquiries. Higher floors are quieter with less traffic noise.
