Have I messed up our tickets

Visiting from the uk in February, 2 families (4 adults 3 kids). We have finally paid off our tickets (through attraction tickets) and I downloaded the tickets. As the kids are different ages/ we may not want to do the same things, I wanted to send the other families tickets over. I added them all as family and friends and sent an invitation my my sister in law for her ticket, she accepted but it wouldn’t let me do the same for my brother in law (it was just a loading symbol) and the kids didn’t have the option to send the invitation.

So as it stands my sister in law has accepted my invitation, her name still shows up on my tickets and passes but it won’t let me download the ticket. Everyone else is still on there.

On our first day can we just go to the ticket booth and I give them the attraction ticket confirmation code (it’s a Disney reference) and they’ll print everyone’s tickets? Or now I’ve sent it to her will she not be able to do that?

Sorry, I’m really anxious as we’ve paid so much for them and I’m worried (probably for no reason but the anxiety is sky high!)
