Sharing memory maker

[sdd1841]

Quick question about this.....we are headed down Sept 16 and my extended family is joining us on the 19th. I have already set up my disney exp, fp, etc.....but another member of my family has now purchased the memory maker and sent me a request to join their group on MDE so I can get the pictures too. Love that they are including me but will this mess up MY MDE account, reservations, etc....

Thanks!
