Here are a few suggestions for lodging:  

Option one: Check out the Chamber of Commerce website for hotel information and other ideas: http://www.beach-fun.com  

Option two: There is limited camping in Cape Henlopen State Park where the tourney is held. It is literally steps from the beach and they have showers etc. If Henlopen fills up, there are some other camp sites a short drive away. (Just call the state park) 

Option three: Rent a house for a week or a weekend. Many WRFC players did this last year. We crammed a bunch of guys in a condo that was 100 meters from the beach. There are places all over for rent. You could obviously get one for the week but they usually run from Saturday to Saturday rentals. We got one Friday to Friday. One realtor is Jack Lingo. Just check the internet.   

So you know …  

Cape Henlopen, where the tournament is held, is at the north end of the Delaware beaches. Basically, the beaches run north to south as follows: Lewes (family area), Cape Henlopen (state park), Rehoboth (family beach and boardwalk), and Dewey (where the best bars are). From Dewey, it is only a 10 minute drive north to the tourney. The trip definitely takes longer with Saturday morning traffic, but your hangover is gone by the time you get there.

Why should you come to the tournament? Besides the fact that it is at the beach, the tournament is a great way to end the 7s season and begin your fall 15s season. It is also a great vacation location due to its proximity to Dewey Beach (less than 10 minutes away). Dewey is famous for its nightlife and debauchery. The small beach town is peppered with locations to drink and meet that special someone.

And one final reason: Cougars! Dewey is also famous for the abundant cougar population (older women on the prowl for younger men).
