My parents and my other halfs parents have their anniversaries pretty close to each other. I've been wanting to go to the Baltimore aquarium for months and have been wanting to take our family there (they love fish and his parents have never been there) Long story short my other halfs dad ended up in the ER last month with heart issues and my grandma who would also go with us has been having breathing issues as well. I was thinking we could take them on a lunch cruise (since it wouldnt involve to much walking) but his parents will be going on a real cruise next month. I don't want to do an ordinary dinner celebration or anything too expensive (I'd like to keep it less then 50 per person), even though that's what it might end up being.

What do you do for your parents anniversary or how to you celebrate with people who are older?
