Yes, by all means tell someone! Oh and as you may or may not be aware, the Ticketmaster or concert venues release more tickets closer to concert time ( usually) and maybe by some AmEx miracle some great seats will wind up in your hands..
you might also keep checking online at Ticketmaster..put in best available and you never know .......
I just tried it at their site and 2 seats in section BB came up ( center stage).. wish I was in HI I'd grab those
ALOHA!
