That's me - I really miss mini-golf! I know, most people would ask - why????
Oddly it is the one thing I miss most on HAL and Celebrity. It's just one of those things you can wander over to any different points in the day or night and evening and play - and unlike Shuffleboard or pickleball, there is always space for anyone who wants to play.
I think it is viewed as a kid's activity and takes a fair amount of space which I guess is why it is not there on HAL or X, but I do miss it. On HAL I have accustomed to it is another few laps around the promenade instead of minigolf, but I still miss it.
