10. Get creative with "staycation" plans. If you decide to stay home to save money, then Ornella Grosz, author of Moneylicious: A Financial Clue for Generation Y, suggests using sites such as Groupon, Living Social, and Bloomspot.com to snag the best deals in your neighborhood.
11. Rethink the kids' getaway plans, too. Ulrich says it can be easy to continue signing up each year for the same summer camps, especially when early sign-up means a discount, but she says a change of routine can save money. "Research new camps now for next year and ask around with other neighborhood parents for their take on other, possibly less-pricey camps," she says. Plus, she adds, with so many new educational camps, signing up for a school prep-like camp could result in lower tutoring costs during the school year.
12. Make use of credit card perks. Whether you're headed to a big city or beachside retreat, you might be able to rack up points on your credit card that will help pay for the trip. That includes discounts on airfare, hotels, luggage, and even camera equipment, says Descano.
Impart money wisdom to the younger—and older—generations.
13. Take advantage of family time. The National Foundation for Credit Counseling's Gail Cunningham says family time is the best time to share personal-finance lessons or to set a good example when it comes to budgeting and saving. The organization's 2012 survey found that 44 percent of respondents said they learned the most about money from their parents.
14. Use everyday experiences to share those lessons. Susan Beacham, founder of Money Savvy Generation and creator of the popular Money Savvy piggy bank, says that when her family stopped at diners on long summer car trips, she and her husband would offer to give their children the cost of the soda if they opted for water instead. "They took the money and we avoided kids hyped up on sugar," she says. Similarly, instead of buying souvenirs haphazardly, she and her husband offered their children a set amount of cash and let them decide what to buy—and she says they usually came home with some cash left over.
15. Talk about giving back. The Money Savvy piggy bank features four slots: saving, spending, investing, and giving, which emphasizes to children the options for their money. Beacham suggests talking about how they can actively donate through non-financial methods as well, such as teaching another child to read or helping a local senior get online.
16. Read about money. Your local librarian can help you find money-themed books to add to your child's summer reading list, says Beacham. Since summer generally means no homework or sports, there's more time to read and talk about those lessons, she adds.
17. Bring up finances with your own parents. Descano suggests using time with extended family to ask parents about their own future financial plans. "These conversations may not be easy to have, but it's better to have them in a relaxed setting and with an open mind than while stressed if an emergency arises," she says.
Shop with purpose, and with coupons.
18. Take advantage of summer markdowns. Patio furniture, grills, and other summer items tend to see big price drops at the end of summer, as retailers focus on fall inventory, says Grosz. If you planned to buy those items anyway, timing your purchase can result in big savings.
19. Spread out back-to-school shopping. Summer clothes tend to go on sale by mid-July, and school supply sales can start when the weather is still hot, too, says Cunningham. Families on tight budgets can spread out purchases over several months, to avoid a jumbo credit card bill in the early fall, she adds.
