Is there a widget that will allow MULTIPLE people to book for the same day and also allow me to BLACK OUT days?

The problem with BOTH of those widgets is they don't allow me to let 15 different people book a tour.  As soon as someone books then it locks out the other people.  So for me the "Date Picker" widget is the only thing that works.  But the problem with it is it doesn't allow me to BLACK OUT certain dates when I don't want to run the tour. Is there a widget that will allow MULTIPLE people to book for the same day and also allow me to BLACK OUT days?

I am not sure if I understand your query correctly. Do you mean to allow some number of tours on the same day that is allowing other people to book the tour and then disable the dates? Or are you referring to enter multiple traveler information on the form for the booking? 

Please provide more information on your requirement so that we'll see what best we can do in this regard.

Thanks!
