Go to the Travel Recommendations forum on this site and browse through for WWBA information. There has been some recent "clean up" (deletions) on the forum, but there is still some good information. You may want to repost your question there. It will start a "new" reference for this topic!
We ate at the Marietta Diner as a team with parents (recommended by PGStaff) and you could easily split meals. Desserts were tremendous. There was also a great BBQ place near Kennesaw that you eat on picnic tables inside.
Our team stayed at the Comfort Inn and Suites in Kennesaw which was a very new nice hotel. Had an indoor pool (which seemed like a negative at first, but all was good) and a very nice patio with fireplace outside. Breakfast was good. WWBA has required lodging which you can find the link on the PG site, and remember that not all games (one, maybe two if you are lucky) are actually played at the East Cobb Complex.
Your team should book your hotel early to get the best selection. Q/Q rooms and suites at hotels will sell out first. Having a hotel with a washer/dryer was a big plus for our team.
I love the website
www.tripadvisor.com for hotel recommendations and reviews. Also, it ranks hotels and restaurants. It may help in hotel selection and ideas for where to eat.
Our players went to the Andretti Carting experience (in Alpharetta), which was a little pricey, but they had big fun. The hotel shuttle took some of the players to a nearby bowling alley and later picked them up, which was a nice treat for the parents. We tipped the driver well
. There is a movie complex (in Marietta I think) that shows movies for $1.75. Makes for a cheap evening.
