There are a few discounts available that can save you big time.
1. www.loscabospassport.com is one site where you can purchase a discount card. Info on the card are available at the web site. I use it and love it.
2. www.loscabosguide.com This is a vocher program thats excellent. You purchase the Voucher and save from 35% to 50% on activities and restaurants. If you dont use the voucher send it back for a full refund when you get home. Great deal and easy to use.
3. The third site is undergoing some changes and will hopefully be up and running soon. www.thecabostore.com
