Its only a bed for the night - I wouldnt worry.
I had the last room (read: last chicken in the shop) in the one I booked, not got an en suite bathroom, its across the hall, but only our room has a key - so its private, but you have to cross the hall to get to it.
Besides, we will be out for a few drinks on the Sat night, going to sleep, then getting up to go driving on the Sunday - it doesnt have to be the ritz, just a bed for the night.
