I have a question. the person who sets up the donation page is the only one getting in w/o park admission correct? i'm still down to do it either way, i might have friends n family joining me that day
Correct - if you want to bring someone with you, they also need to register a page, make the initial $25 donation, and commit to brining in another $75 worth of donations.
I would encourage you to recruit as many friends and families to do it as raising the additional $75 shouldn't be too difficult!
