If you are looking for machines guest will love you can't beat a Skeeball Machine, Shuffle Alley and Pitch & Bat in the gameroom. But if you are looking for machines that you enjoy a pitch and bat gets old very quickly.
We have the space so we have machines for us and machines for guest but if you don't have space for at least 8 or 10 machines a pitch and bat waste a slot you could have another pin to enjoy in.
If you don't get an earlier one (with running man unit) the next best machine is Slugfest. We had both Pennant Fever & Slugfest and I liked the look of Pennant Fever but Slugfest has better sound and is more fun overall
