With Hyatt’s Instant Win Weekends promotion, guests have the opportunity to win a family reunion getaway for up to 20 people, including air transportation, to a Hyatt Hotel of their choice.

Through Aug. 30, any guest who checks in using their MasterCard card on a Friday or Saturday will receive an instant win game piece, and will also be entered into a MasterCard sponsored promotion that is awarding a full year’s use of a weekend home.

Each game piece gives the holder a one in 10 chance of winning a prize. Six thousand prizes will be given away, including the family reunion getaway, 25 weekends for two, MasterCard gift cards, or 5,000 Gold Passport points. Everyone participating will also receive a certificate worth $100 off a future two-night Hyatt stay.
