•One winner will be drawn for every package holiday presented in the Estonian Air and Estonian Tourist Board e-draw (Hotel Go Spa, Vihula Manor, sea kayaking and bog-shoeing adventure and smoke sauna in Haanjamaa).
•Every winner will receive a tourist-class return ticket to Tallinn on a direct Estonian Air flight of their choice (numbers depend on the specific lottery prize package – the quantity of return tickets may vary from 1-4).
•Reservations for flights should be made at least two (2) weeks prior to the travel date and are subject availability.
•The draw for the winners will be held on 5 April 2012. The winners will be contacted by e-mail during the following week.
•All prizes must be redeemed by 30 December 2012.
BTW - my guess, since the rules don't indicate otherwise, is that this is open to people outside the U.S. as well.
