Possible destinations for 85 yo mom

My 85 year old mom has never been to Europe. She and my dad just couldn't afford it, and really, none of us could have easily afforded to take them with us.

So now my dad is gone and it's just her, and today I mentioned we were going to Amsterdam this fall, and she said how much she'd love to go, a well-off friend of hers went recently and told her about it.

Truthfully, I don't know how we would manage taking her. She has multiple health issues that are very unpredictable. She can be fine for days or weeks at a time and then in such intense pain she can barely walk. I also found out today that she may be needing a pacemaker.

She's very lively and, adventurous for her age, but the only way that I could see it working out is if she came with just my husband and I and we devoted that trip just to her. Going at her pace only, and the trip being all about treating her to a once-in-a-lifetime trip.

Having said that, are there any particular countries or itineraries that might be possible for this kind of scenario?
