The other thing I would suggest if you are going the Premier Inn route, is to decide what you want to see and be prepared to move hotels so that you avoid travelling to and fro. They have branches everywhere. And book the fully flexible rate initially, slightly more expensive but you can cancel up to 13.00 the day before. I would say the rooms are similar to the AS resorts, some slightly smaller. I don’t think that their restaurants are great, so I would avoid eating in.
Are you going to try ‘real’ traditional English food?
