In my opinion you would be better with 2 interconnecting rooms a King to a twin.
The suites are nice but the Lounge is smaller than the bedroom. The lounge has 2 sofas and a large coffee table which takes up a lot of space.
I do not think the lounge sofas are actual sofa beds although I may be wrong and best to check with hotel but if not with rollaways in the lounge you would not be able to move.
