You could be dropped off for free in the mid term car park and then get the free bus to the terminal but I would also be inclined to walk from the Holiday Inn and would say it was more like a 6 or 7 minute walk.
When airside an oasis of calm with seating can be found if you head for gates 1 to I think 6 or 7. Before you walk downstairs there is a lounge with a small cafe but you don't need to use the cafe to use the seating. From this lounge no gate is more than a 6 minute brisk walk even if you have to walk all the way back. This lounge has flight screens so you can keep an eye on your flight.
