My mom and I (plus Dutchy) decided to meet up at Thanksgiving Point this year to go to the tulip festival. Neither of us had ever been before, so we didn't know what to expect but we had a lovely afternoon strolling the gardens- in perfect weather. Not too hot and not too cold.
We debated on getting a yearly pass but decided against it because it's just too far to drive every week and that's what it would entail to get your money's worth.
