After You Add the First Item On the Correct Date and Time, At The Bottom of Screen It Gives You an Option To Add Another Product. This Can Be a Different Type Of Product For Example: 1st Item is a 24’ Pontoon Boat for July 4th at 10am. You Can Then Add Another Product That Is a Different Size of Boat or Waverunner for The Same Day to the Same Reservation. It will Not Allow 2 of The Same Boats at The Same Time to Be Booked. You Have to Call the Office to Do This. If You Want The 24’ Pontoon Boat July 4th at 10am and 2 Waverunners at The Same Time, You Will First Add the Boat, Then Add The 1st Waverunner at 10am and the 2nd at 10:05 am. Multiple of The Same Items Have to Be Booked 5 Minutes Apart. You Can Book the Same Boat for Different Days. So, Let’s Say You Want a 24’ Pontoon Boat on July 4th at 10am, and another on July 8th at 10:30 am, and another on August 9th at 10:15 am you can do this on the same reservation. If You Want the Waiverunners To Go Out The Same Time as The Boat and You Can't Do it Online Then You Can Send Us An Email or Give Us A Call. We Will Try To Accommodate The Request. Again, If You Have Issues We Can Book It Over the Phone for You.
