OK, and one nephew.
Four nieces and one nephew will be up for the weekend, the first time I've had all of them up at one time. Oughta be interesting.
Question is: How do we keep them entertained?
Several suggestions included the pumpkin thing at Greenbrier, the maze thing at Mayflower and a putt-putt/go-cart track here in Conway.
No idea yet. So, still taking suggestions ...

Assuming...
...that the weather is nice, a trip to the Little Rock Zoo is generally an inexpensive way to spend the day with that many children. When the weather is cooler, most of the animals there are actually visible.
'Toy Story & Toy Story 2 in 3D Double Feature' are showing at the Rave this weekend, as well as 'Cloudy With a Chance of Meatballs 3D'.
And if I read correctly, it looks like Silver Moon Cinema will present 'The Wizard of Oz' tomorrow night. Could be a beautiful night for such an event.
Good luck! : )
