Go to allearsnet.com. They have a list you can print of all the pressed penny locations and which designs are at each. That way you know where to look for them. This was our kids souvenir for the trip. Also, go to your bank before going and get rolls of quarters and pennies, so you are not hunting for them. Then, get a large and small tube that mini M&M's come in. The large tube holds the quarters perfect and the small tube for the pennies.
