I am staying at the Charles Inn which is about half mile away..am driving up from MA to get my mom and take her and did not want to have to drive her home that night...

Does anyone know where we pick up the fan club member tickets for this show?  I am driving up to Newport from MA to get my mom and go to the show and if I have to stop in Lewiston or somewhere to get the tics I need to know as gonna be a long day of driving as it is.
I am not sure if the Waterfront has a box office or not?
Thanks
