Had a similar but different experience with Google Maps for near airport hotels at Gatwick. Luckily I decided to ring the hotel to confirm my suspicions that GM was wrong.
Turns out GM were correct. The hotel despite being directly over the road from the airport terminal end had no pedestrian access anywhere - you could not physically (safely) go for a walk anywhere from that hotel. No footpaths anywhere. Fences blocking the way immediately adjacent to both sides of the hotel and the (level) start of a motorway on-ramp in front. So even to drive to the terminal required a several km detour onto the motorway, off again, on again in the reverse direction and 2nd exit vs 3rd exit at the roundabout.
BTW - never stayed there. Preferred Premier Inn a pedestrian crossing away from the terminal for normally GBP 39/night (if booked far enough in advance) sleeping up to 4.
