allearsnet says they open at 10am.
Fantasia Gardens is right across the street from the Swan/Dolphin. Winter Summerland is down by Blizzard Beach.
It's been several years since we've played them but they were a lot of fun. Fantasia Gardens was more challenging. We only played the "summer" course at Winter Summerland and really enjoyed the theming (think Santa with a sunburn and you get the idea).
