A free chocolate tour . . . awesome!
Best during the holiday season when the cactus garden is lit . . . however can be incredibly crowded so you end up shuffling along behind twenty doublewide strollers. I haven't yet figured out the best time to go, when the lights are up but the crowds are not yet crushingly awful.
The gift shop is pricey and the free chocolate given out at the end of the tour is definitely not representative of their best offerings.
