Best known are the high school reunions, which remain the most popular, but other types of reunions are gaining in popularity. Family reunions are increasing in number because family members have become spread out and are not as localized as in decades past. Also, people are living longer and the size of families has grown. The average family reunion will have from 150 to 200 attendees. Reunions are held for championship teams and people who worked on political campaigns.
Military reunions are also big business.
ITT Sheraton has formed a Military Veterans Network and held a number of military reunion planning conferences. To tap into this market, contact local high schools, colleges and veteran's groups. Some hotels are pursuing the off premise market. Often it is because the hotel is short of space in the property and off premise is the only way to grow and increase business. It is better to rent tables and chairs and build the cost into your price, than to transport everything from your property.
