Let me clear, I think this hunt should be as a group. No way should it be girls going in all directions..
Wow, I am so sorry that a mom was so harsh. I worked in retail for over 30 years. With an attitude like that we would have gone out of business!
We accommodated different things like this over the years. As long as you give the shops you will be dealing with a heads up, I am sure they will be delighted to participate.
Just remind the girls no running and to keep their voices down..
I think the Scavenger hunt is a cute idea. If you do this in a Mall, consider some of the items for them to search for be in the main sections of the mall like a fountain or a sculpture with a hint to look for the next clue. Another clue could be located from the map of the mall, that would lead them to the Clue at a toy store, where they would pick up a small toy that you have pre-purchsed (jump rope for each child), Then the book store to pick up a book mark and maybe a magazine like Spider or another children's magazine (prepaid) for each child. Then end up in the food court at a table covered with a birthday table cloth birthday Balloons,, etc,, Enjoy lunch with a Pizza party/ lemonade and a Giant Birthday Cookie that is displayed with "Happy Birthday (daughters name)" in the display counter at the Cookie shop..
If this seems like a lot of work, consider a roller skating party or a "kidnapping" Our daughter was invited to one of these at about this age. The mom called the moms of the girls invited and said on a certain Saturday morning early.. 6:00 am, they would drive by and "kidnap" our daughter. I was to answer the door and let them come in and wake our daughter up. They then went around to the other houses and picked all of the guests.. In their pajamas and took them to have an early breakfast and celebrate the birthday girl.. They went to a local restaurant that is open 24 hours. At that tie in the morning, there were not many people there. They are famous for their pancakes. The girls all knew there was a party on that day, but thought it would be in the afternoon..
The photos are so cute. Yes, their hair is mussed, they look half asleep.. When the girls graduated from High School, we were able to recreate that group of most of the girls for a photo.. Precious.
