We are currently booked & have linked reservations with my BIL & SIL. I can see what they have purchased as far as dining & excursions go, but can't see any of their personal info. When I go to look at new excursions to book, all of our names are listed & I have to select the ones I want to purchase for. My SIL says she can see our reservation as well, & the same info about choosing who to book a new excursion comes up on her end, too. Don't know if that helps you or not!
