I doubt there are bouncers at the door of the hospital checking for ID, just go and see her. If she is alert and wants a visit, great! Be prepared though if the family is there and won't admit you, to just leave a card or a keepsake.
I doubt if it happened like that. It's at least as likely that when the relative went to the hospital the patient was in no condition to see her and an unfortunate breakdown in communications took place. And IF that's more like what happened - of course we can't know - then the OP needs to repair communications first and foremost rather than go straight to the question of whether she has a right to demand access. It can't be in the interests of any of them to start picking fights.
Try talking to your niece and find out why first, as was mentioned earlier, the visit may confuse your sister. If that is not the case ask her politely, let her know you would like to say your good-byes, most people understand how important this is.
I can readily imagine a) that your sister is not up to emotional follow-up on your reunion; or b) that your niece cannot handle your reappearance on the family scene right now, while she is coping with her mother's terminal illness; or c) both; or d) that it's nothing to do with you personally, it's just that they're already overwhelmed without adding further complications.
Perhaps the best thing to do would be to send a card, with or without flowers, to your sister and tell her you are thinking of her and would love to see her if she feels well enough for a visit. Give the ward staff your contact details, too. And send your niece a compassionate message telling her the same. Then let them be. If you don't make yourself a nuisance to your niece she's more likely to keep you in the loop.
I'm not unsympathetic to your feeling, perhaps, that you've only just found your long lost sister and now, sadly, her time is short; but you must put her first. I'm sorry for your situation all the same. Best wishes, please update.
Her beau of 15 years called me from his cell phone in the hospital parking lot. He'd taken the morning off of work, bought her some flowers, went to the room, seen the sign, and went back outside to his car, confused. I had him sit tight and phoned the nurses station. They said that was what she wanted, but they didn't know why either. The nurse assigned to her went to her room and asked if he could visit, and she said "yes, of course he could!". She was very happy to see him and loved the flowers, ...(?). Later that day I was due to go take her some things, sign still there, I checked with the nurse, of course I was welcome. Same when our Dad and Stepmother from out of state came. Not sure who wasn't welcome. I'd speak to the nurses, have them check it out, let your Sis and the medical staff have the final word, not the niece. You just never know what is motivating the niece, this just isn't the time to be playing politics if that is what is happening.
I think the family has a right to their privacy at a time like this, and you admit you have not been part of their lives for at least twenty years. I understand your need to maintain this connection and make up for lost time, but in my opinion it is a self serving desire and perhaps not in the best interests of your sister and her family.
