Spanning 5,000 oceanfront acres on the southern tip of Hilton Head Island, The Sea Pines Resort has all the ingredients for a laid-back family getaway: five miles of beach, three golf courses, a racquet club, equestrian center, 20 miles of bike trails and nature paths, and its own forest preserve.

The resort's Escape Package, available for week-long stays through September 10, serves up a 15% discount on weekly vacation rentals.  It also includes a resort credit, free kids' meals and some other extras. But is it a good deal for families? We crunched the numbers to find out.  The package includes:

• Seven nights in a villa or home (worth $990 for a two-bedroom Heritage Villa)
• $100 resort credit  (worth $100)
  
• Dinner for two kids under 12 ($20/child x 2 kids x 7 days = $280)
  
• One round of golf for two kids under 12  ($50/child x 2 kids = $100)
• One 90-minute dolphin excursion for kids under 12, per paying adult ($10/child x 2 kids= $20)
  
• One family portrait session on the beach (worth $125)  
• Choice of eco-tour or activity for two people at The Sea Pines Resort or Historic Honey Horn & Coastal Discovery Museum (average $10/person x 2 people = $20)
• Access for two guests to the Harbour Town Lighthouse (worth $5/person x 2 = $10)
  
• Unlimited use of The Sea Pines Resort Fitness Center (always free)
  
• Two hours of tennis per day at The Sea Pines Racquet Club (always free)
• Wireless internet access in all accommodations (always free)

When we added up the value for all the package components, a seven-night April stay for a family of four came to $1,645.   If you booked the package, the same stay would cost $841—a whopping $804 less. That's a savings of nearly 50%!  

Look beyond the 15% discount on the lodging.  What really makes this package are the value-added extras. The free kids' golf and free dinners alone will save you close to $400, and if you use the resort credit toward your other meals you'll chip away even more at your overall spend.

Deal or no deal?  Definitely a deal! With this package, you're saving 15% right off the top. Add in those extras and your savings skyrocket to 50%.

The fine print: The offer is subject to availability.  It requires a Saturday arrival, and a 30% deposit 90 days in advance of your stay. Book online or call 866/561-802 and use promo code "Escape."
