We did both courses in 2021 (Fantasia in the spring, Winter Summerland in the fall). Both were fine, nothing was in shocking disrepair, but it is definitely easy to see that they are older courses.
Our favorite offsite mini golf courses are as follows, in order of preference:
Hollywood Drive In Golf (both courses)
Congo River
Pirate's Cove
*all in a three-way tie for first, so a "favorite" would be based on your preference of theming, and
*all 3 equal to or better than Winter Summerland, and
*all 3 we would rate higher than Fantasia
Hawaiian Rumble
Lost Caverns
Gator Golf
