For budget options I find the Premier Inn is ok, it’s strictly speaking off site but is about 10 minutes walk from the north terminal, though not if you’ve got a trolley load of luggage. There’s also one bad road to cross, a slipway down from the departures level, although last time I was there it was closed for renovation so no problem. There is one more road to cross beside the garage adjacent to the hotel, but visibility is ok and it’s not too busy. There is a hotel bus service but I’ve never used it. Hotel itself is the usual offering.
