I arrived around 11 am there was plenty of parking and no crowds. It took about 30 minutes to complete the self guided tour, checkout both gift shops and your the cactus garden. They offered samples in both stores and everyone was very friendly.
The prices are a little steep. Overall good place to bring the little ones to burn off some energy and grab a small treat. My toddler enjoyed it and I enjoyed discovering and pointing new cacti to her .
