Castle mini-golf is certainly not the only mini golf in the area; but it is a nice one.
The course is interesting and there are no dull holes.
You have the courses with obstacles, height differences and quite some 'short-cuts'. Only negative is that the short-cut is not always the best option; but it is impossible to know in advance; something which defeats the purpose.
In this area of Florida there is always a chance of (heavy) rain; castle golf gives you a rain-check though, so no troubles there.
Adults pay about 12,50 with tax; not that cheap in my opinion.
But it was quite some fun for 45 minutes.
