I am actually going to volunteer there all next week with my daughter whose school requires 60 hrs of community service and 1/2 of it has to be in the community not on the the school campus, so she will start school with 39 hours already completed. I definitely think you can go and volunteer for just a day or two while on vacation. Most shifts are broken up into three hour windows starting at 7:30 am so you can do that before heading to the parks or if you are rope drop people you can volunteer for the lunch/dinner shifts. They have a lot of availability to work in the cafe and then other shifts have age requirements where they need to be over 16 or 18. It will be indicated when you sign up. I was all set to volunteer there with my three kids early in the summer there but I got covid and there was no way I was going to risk getting those kids and their families sick so we had to cancel, not knowing if my kids were going to get covid after I did. My other two started school this week and she doesn’t start til the 29th so we are doing a mommy daughter trip.
