I'm not sure the lounge will be open now, I'd call and ask its not at the bar. Riva was only open during June and July.
It was really crap this summer, so you're not missing much. Big downgrade on previous years "Covid", I've seen better breakfast's at HbH. Lounge really poor. They basically couldn't give a hoot.
The hotel is going down the pan. I can't see a future for it. I wouldn't be surprised to see it deflagged at some point.
Didn't even bother with the pool, as only 1/4 of it is in the sun.
