Wen I play at a country club, I'm all over the place. I do guitar solos at tables and in different locations, using a wireless.
For events, I use a Roland Lucina with a wireless. Not a great piano sound, but gets the job done.
Sometimes, I go from lounge to dining room, using two completely different set-ups.
And, I play outside for picnics/outside meetings. I use Various wireless and battery powered pieces. It's fun to switch up!
