Cost is always a major factor when considering attending a family camp! Here are a few ideas that you may find helpful:
1. Check for scholarships (examples: your local church; or a conference if your church belongs to one).
2. Check whether you can pay your fees in 2 or 3 installments rather that all at one time.
3. Check whether there is a discount for early registration and/or for paying your fees in full by a specific date. If so, take advantage of that!
4. Great gift idea… camperships, $$ toward registration fees (parents, grandparents, relatives often need Christmas or birthday gift ideas… suggest this to them!)
5. Combine a $$-gift with something that can be used at camp (suggestions: a disposable camera & small album for photos of the event; a beach towel; a water toy; a cap or t-shirt; a book to read; a puzzle book, a journaling notebook, etc.)
6. Designate a “loose change jar” in your house for coins–they add up faster than you might think!
7. Try a family fundraiser (buy a box of mini M&M’s tubes; eat the candy; then save quarters in the empty tubes–a tube holds $14′s worth of quarters!) Ask friends and relatives to help!
8. Are your kids old enough to babysit, mow lawns, do odd jobs? Teach them to set aside a percentage of what they earn to go toward their camp fees.
…perhaps these ideas will prompt you to think of other ideas to help make your camping experience more affordable. ) I would be interested to know if you come up with additional ideas that work for you 
I thank you humbly for shranig your wisdom JJWY
