It is grand to see not only a 18 hole course outdoors but an 18 hole indoors as well. The putting is fun as there is more than 1 way to go and there is a few secret routes sure to give you good score.
Get an early tee off to avoid the mobs. Pay for both courses at the same time. Watch out for pirates. Take a jumper - just in case. Bring your 'A' game. Be prepared for lots of fun.
