Party

• Throw a party for your parents' wedding anniversary. Decide if you want to have a surprise party or if you want them to know about it ahead of time. Depending on your budget, pick a theme. For example, a backyard BBQ would work great for an inexpensive party. Recruit some siblings or close friends to help. Grill some of your parent's favorite foods. This can be a fun, casual experience for everyone.
  
  If you are looking to throw a more formal occasion, rent a reception hall and re-create their wedding reception. Higher a DJ to play music that your parents love. They can even dance to their "first dance" song. Blow up a picture of them from their wedding and put a mat around it for the guests to sign.
  
  

Vacation

• Send your parents on a fun vacation. Consider a cruise through the Caribbean or an Alaskan cruise. You can find many all-inclusive getaways to places such as Mexico or Jamaica. Be sure to consider your parents and send them to a place you know they will enjoy.
  
  You can send them on a weekend getaway to a quaint B&B in a historical town. There are many B&Bs in just about every state. You may be able to find a B&B within driving distance of their home.
  
  If you don't have a lot of money, consider sending them on a relaxing spa day. You can treat them to a couple's massage, champagne and lunch.
  
  

Scrapbook

• If you are not able to throw a party or send them on a vacation, simply make them a scrapbook. This is a sentimental gift that your parents will treasure. Go to a craft store and pick out an album, colored paper and various decorations for decorating the pages. Take old pictures of your parents' life together. Include wedding pictures, holiday photos and family pictures. Have each sibling write a personal letter to your parents. This scrapbook will be very special to your parents to look back at.
