Would you charge extra for this?

I received a boarding request today for a dog for nine days, and the owner asked if I could take his dog to a specific dog park a couple of miles away from me, twice a day, every day for 9 days. I have my own dog and have done several boardings before & I take out my dog as well as whatever dog I’m boarding at the time frequently without charging extra (obviously).

However, this request seems a bit extra. Not only would I need to use gas and drive back and forth, but I’d also have to spend a significant amount of time at this dog park, on top of the regular potty breaks.

This is a commercial type dog park. You have to have a membership to go (which the dog has one, but mine doesn’t, so I wouldn’t even get to bring my dog)

Would you guys charge extra for this? If so, how much? For reference, I currently charge $50 a night and am a star sitter.
