Impact Arena in the Don Muang area hosts many top international acts and events (Sting, Elton John, etc.)

The taxi there cost 80 baht, plus a tip for about an 8km journey of about 20 minutes from the Pak Kred area, reasonably close to the venue. Getting there is no problem.

But to get back, you may encounter rogue taxis that want 500 baht for the same journey because now patrons with limited options for transport are a captive market with hundreds of other competing customers.

Knowing this in advance will allow you to make alternative arrangements.
