Does military still get in free once a year?? I remember we did this about 2 years ago but haven't really heard much about it since? And is there a limit as to how many dependents you get in for free as well? 

Yes once a year and I THINK it is 4 people, but it might be 5 people total.

Yes, if I remember its 4 dependents. If they are over the age if 10 the must have a military Id. 

It was only 3 dependents! :) Heads up for the future!
