Tip 1
Most of the museums have a free monthly entrance day or sponsored entrance days (Target Day for example). By planning and visiting their websites, you can take advantage of these opportunities. Bank of America card holders get free entrance at 70 museums across the nation the first Sunday of the month. Check the list to see if some are nearby.

Tip 2

Parks are wonderful places to discover with children. If you visit them on the week-ends, you will most likely see street performers and will be able to enjoy nice performances for free. (although I would always encourage people to tip).

Tip 3

Churches (although you have to pay to visit St Paul and Westminster Abbey in London) are full of treasures that one can enjoy for free.
Tip 4

Pick a destination known for their free museums entrances: Washington DC or London. Most of the London museums are free and what a pleasure to be able to take our children to the Natural History Museum twice in a week without thinking of the price.

Tip 5

Do a home swap: here is a big saving. And if you are lucky, people may even agree to let you borrow their car too, helping you save on car rentals.(www.homeexchange.com)
Tip 6

Use your credit card rewards points: my husband flew twice to France without spending a dime. And because I pay my credit card balance at the end of every month, that card does not cost me anything.
Tip 7

My last piece of advice for the travelers would be to register to newsletter or blogs specialized in traveling. For the San Francisco Bay Area, you have my blog www.travelismorefunwithkids.com , www.friscokids.net or www.inflightout.com that track good deals or free opportunities. By doing this, travelers will always know where to go without spending much or anything at all. For example, in December, I wrote about what to do in the Bay Area for free. People could entertain their families for the holidays almost every day without spending a dime.

Education is the key and registering to newsletters from blogs or websites that do the work for you is the best way to save on your trips or staycations.
