If anyone wants to go to Diamond Valley, I got some advice for you. If you go on the weekends it will be SUPER crowded, so be sure you make an advance for a reservation for the boat before you go! Second thing is check the Diamond Valley site for any special promotion for the coupon. Last thing is if you go on Wednesdays it's half price for renting boats, but you will still need to make a reservation before you go. Good luck!!
