Adannae, 11, from London was one of them. She said:
"Schools should have got the day off because it's a special day for the Queen too, so they should get a day off to at least pay a little bit of respect to her."
A final farewell
After the service the Queen Mother's coffin was placed in a special car for her final journey to Windsor.
The car drove slowly past her home on the Mall and Buckingham Palace.
Prince Charles sat quietly in the car immediately behind the vehicle carrying the coffin.
