Bristol has two Marriott hotels, and although the Marriott Bristol Royal doesn't have a lounge, it is a very nice hotel just off the city centre and close to both shopping and restaurants.
I would avoid rooms on the lower floors on the Water Shed / Road side we had 1106 and it was very very noisy all night however they did offer free parking. Otherwise a very nice place to stay.
Discover an elevated experience at Bristol Marriott Royal Hotel, perfectly located in the centre of the city. Enjoy renovated modern rooms and suites, a 24-hour fitness centre, elegant event venues and a Miller & Carter steak restaurant.
