Not a recommend to stay but a definite stay away from the Britannia - offers park and fly, but I suggest sleeping in the car before your flight would be better than in the hotel.
Restaurants are 'so so' for a feeding as a saving grace but the state of the place is not acceptable to charge guests.
Lots of alternatives - but maybe a look at the info at

Hace a peachy time...
