I did an almost sleepover party for my DDs 7th birthday. It was great!
All the kids came in their pjs at 4pm. They played, opened presents.
I bought pizza bases & they made their own pizzas. Then they had Icecream cake for the cake but I had lots of toppings so they could make Icecream sundaes.
After that we made popcorn, set them all up on the lounge with blankets and cushions and they watched Tangled.
Pick up was 8.30 from memory. For party bags I sent them all home with milk and cookies (just long life containers of strawberry milk from the supermarket) and biscuits I baked.
It was wonderful. The girls loved it (we had 4 little girls) and it was just like a sleepover but without the stress of scared little girls staying the night.
