I don't think you can see the EWP from inside the lounge. Suggest you go outside on the TOTWL back deck (behind the bar) if you want to see the EWP. IMO, you won't need any music to be piped in. You should hear it just fine from up there. We could hear it inside our top floor room with the balcony door closed. (The room over looked the lake).
There's a door to the back deck on the left side (facing the bar). Not many people go out there so you may have it all to yourself.
