Dear L.,
What you serve depends on the time of day and duration of your party. If you want to keep it simple or are on a budget I would suggest cold cut platters with mini breads, buns, bagels, assorted condiments, veggie platters w/dip, bowls of chips/dip and nuts. Beverages of choice, coffee and cake.
If you can afford to have it catered, go for it, less work and stress for you.
If you can have a DJ that’s always fun, they can play the music that's been popular in your husband’s life. If not you could play your own CD's or put someone in charge of music.
I'm not much on games for 50th birthdays; people generally enjoy catching up and visiting. You might create a collage of photos of your husband starting from birth to now and significant occasions in his life. We did a DVD with lots of photos set to favorite music.
I would also make or have made a party favor as a memento of his day. We did M&M’s with the number 50 on one side and a photo on the other side (yes they can do that), and put them in plastic containers. There are lots of good ideas for party favors.
Hope you have a wonderful time!
PRESENTS! Let your friends bring cards and/or presents...some 50th presents are hilarious and lots of people give gift cards to nice resturants...it's his big day!
Blessings….
