Water was our theme this week in NYC—specifically sailing on it. We posted about this weekend's FREE North River Historic Ship Festival in Tribeca, where you can tour and ride on vintage vessels. For landlubbers there's the new Shipwreck! exhibit at Discovery Times Square filled with interactive stations that give kids a peek at historic life on the high seas. And of course we're particularly excited about the very special family cruise we're hosting next Saturday, June 29. Join the Mommy Poppins gang on the Clipper City Tall Ship as we sail through New York Harbor and enjoy songs and stories by Bill Gordh, an eye-spy scavenger hunt led by educators from the DiMenna Children's History Museum and other nautical activities. Space is limited so book now. Bonus: If you buy your tickets by Monday, June 24, you'll be automatically entered to win great prizes like passes to the Liberty Science Center and a family four-pack to Wanda's Monster the Musical.

Outside the city, we were all about summer fun. Our brand-new Westchester site posted about a series of FREE summer block parties in Mamaroneck, while our Long Island site uncovered cool kid-friendly activities at grown-up destinations like the Belmont Racetrack and South Fork Wineries. Of course you can find plenty of other seasonal inspiration on all of our sites and in our NYC Summer Guide.

It's your last chance to enter this week's giveaway, which is particularly awesome: Four orchestra tickets to A Christmas Story the Musical at the Theater at Madison Square Garden. I saw it with my seven-year-old last year and it's great fun even if you've seen the movie a million times. And there's just a few more days to contribute to the Mommy Poppins Kids' Activities App. We're 60% funded and, if everyone who reads this contributes $2, we will make our goal. Donate more and you'll earn some really cool rewards like brand-new Mommy Poppins T-shirts and tote bags.

Here's what else we covered this week on the NYC site:

With so many great summer day camps in NYC, finding a good one isn't an issue, but it's hard to find a camp that's as great a deal as NYC Parks Experience Summer Day Camp at just $500 for the entire summer. Usually parents have to enter a lottery to get a place at these coveted camps, but the Parks Department has given Mommy Poppins the inside scoop that there are some select spots still available.

Run by the New York City Parks Department, this seven-week program has multiple locations throughout the five boroughs. Campers enjoy outdoor adventures like hiking in local parks, a variety of sports including swimming, as well as educational activities like field trips to museums and other cultural destinations.

You can no longer apply through the Parks' Department website. The only way to snag one of these spots is with the information in this post. So read on to find out about NYC Parks Experience Summer Day Camp locations with availability, and how you can register your child.

Or check out other hot deals on cool summer camps where kids can engage in a wide range of activities, from chess to pottery to language immersion to circus.

We were all about the new on Mommy Poppins this week. We kicked off a new neighborhood focus for the month, Ridgewood, Queens, we're hosting a new giveaway of a week of cooking camp and we launched our brand-new site Mommy Poppins Westchester. We're particularly excited about that last one since our Westchester readers had been begging for their own site for years. We love giving the people what they want! Now you can find out about the best things to do with kids throughout Westchester County and the Hudson Valley and sign up for the local newsletter.

Over on our Travel site, we rounded up Father's Day family vacation deals to destinations both near (Mystic, Connecticut) and far (the Bahamas). Of course you don't need to leave the city to do something special. Our Summer Fun Guide is filled with fun ideas for Father's Day and beyond, including a bunch of just-added posts like FREE outdoor kids' concerts and performance festivals, and the best new museum exhibits for families.

We made great progress on our Mommy Poppins App as well this week: Our IndieGoGo campaign is almost 30% funded. If we reach our goal the app will be FREE to all so please consider contributing—a donation as small as $2 truly makes a difference and if you give more you get some awesome rewards.
