@D--Richard0 Almost all my guests arrive by air to the airport an hour away and take the bus to my town, so they don't have a car here. It is only a 5 minute drive from my place to the bus station, but a 20 minute walk, and my place is hard to find. So I pick most of my guests up at the station, and drive them back when they leave.
I don't drive them around during their stay- it is clear in my ad that it's a 20 minute walk to town and the beach, so they are prepared for that. If I happen to be going into town myself, I'll ask if they want a ride.
I don't mention that I do this pick up in my listing, as if my car was on the blink, or I couldn't come for some reason, I wouldn't want to be held to it and they could take a taxi. I simply offer in a message when it's a week or so before their check-in, and make arrangements for them to call me when they arrive.
Also, it leads to good reviews, as it wasn't something the guests expected when they booked, and they think I'm so nice for offering this extra perk.
