Parents in the Vale of Glamorgan are telling Heart they're angry at disruption caused by Newport's NATO summit.
Despite it being held more than 30 miles away - schools are being advised by the local council to start later and finish earlier to avoid traffic problems.
Mum Fiona from Cowbridge says it'll be awkward to take her children to school.
She told Heart: "When the school opens a bit late and closes a bit early it means i'm going to have to change all my work arrangements on that day.
"It is going to be a real pain for me".
The advice is being described as "disproportionate" by Vale of Glamorgan MP Alun Cairns.
He said: "We have a situation where Llantwit Major schools are closing which are maybe 30 or 40 miles away from where some of the meetings are taking place.
"Then we have schools in Dyffryn in Newport which are remaining open - they are spitting distance from some of the meeting points.
"It's a disproportionate decision taken by decision makers at the Vale Council and they need to explain themselves.
"There are likely to be pinch points on occasions - that doesn't include any road between Cardiff Airport and Cardiff.
"The only pinch points will be between the Celtic Manor and parts of the city centre in Cardiff and that will be only on occasions".
