Any help with planning a 70th, 50th and 25th birthday party?

For a nostalgic feel to these celebrations it would be nice to celebrate the generations. Use time as your theme and post photos of your grandmother when she was 50 and 25 as well as your mother when she was 25. It would be fun to have an activity where people could draw or describe what they think your mother and brother would be at 50 and 70 years old. In this same theme, it would be unique if you had a progression of time during the party where 1/3 of the time you give the theme and feeling of someone who is 25 where the music would be upbeat and high energy. Then do the same for 50, and 70 respectively. So you would set the music and mood of each generation.

If you just want something upbeat and generic for all ages, use a casino theme since that’s still fun for all ages. I’m sure you can find a lot of good casino theme ideas from doing a general search.
