How I saved money the last time was to rent a house rather than a hotel room.  A hotel room will run about 100 to 150 a day depending on what time of year it is.  A rental home will cost you about $400 for the week for a two bedroom while a three bedroom can be had for $600, further reducing the cost per person.

Another advantage of renting a house is that you will not have to eat out every night.  You can go grocery shopping at a grocery store in Brunswick and store a weeks worth of groceries in the fridge.  Brunswick has all the amenities of any other town, including Wal Mart, and you can pick up groceries and whatever else you might need.  You can cook in your rental house, grill out, eat cheerios for breakfast spending a dollar per person instead of 10 or 20 to eat in a restaurant.

Also, going to the beach is free of course but there are other free options.  You can go on a turtle walk, sponsored by the Sea Turtle Center.  All they ask is for a small donation.  You are not guaranteed to see a turtle lay her eggs but it is a good time.

There are many ways to cut financial corners on your vacation.  A cheap Jekyll Island Vacation can be yours if you just budget creatively.
