My thoughts - I’ve only stayed at the Hilton albeit 5 years ago , was upgraded to a suite and I think I got some drink chits too, I have a c class Mercedes, it’s the AMG version so it’s a bit wider than the standard c class……I had no problems getting in the car park although it was tight yes….after a great meal in the bar I went to the sky bar in the doubletree ( it’s pretty much next door ), I thought it was nice and reasonably priced.
If I was staying again I would choose the Hilton and probably use the doubletree sky bar again…… I quite liked it.
