#5. Indoor Gym/Playground This is actually a great idea if you are hosting more than one or two kids and are short on space in your home — especially in cold weather. Giving kids a place to run around like mad is never a bad plan. They are not free, however, and they are not everywhere.
#4. Rented Equipment You can rent just about anything from a bouncy castle to a cotton candy machine to a big old tent. You will want first, though, to make sure you have enough space, money, and kids to warrant the expense. And, for heaven’s sake, make sure the rentals are age appropriate — nobody wants to put their one year old on that giant inflatable slide. (Or their 16-year-old for that matter.)
