Accessing and editing the sub-pages after RSVPing to an event

I’m trying to design a wedding website, and I was just wondering is there any easy way to access the sub-pages after RSVPing yes or no? So far I’ve had to go through the actual process of RSVPing just to preview what they look like.

I’m currently trying to edit one page in particular. After I click ‘Yes, I’m coming’ to my event in preview mode, it takes me to another page. I can see that I can edit some of the information in the page in the event editor, but it comes up with the message ‘See all your RSVP’d events in your Members Area under “Event”’ and I can’t find any way to remove this message?
