hi
the v-room as LV Jay says is a good place to be you are free to come and go and when i was last there thay stamped my boarding pass to allow this.
the food is good and free with tea coffee etc.
there should be enough to keep your children amused as there is a games room with internet access and games consoles and a soft play area for younger children.
there are also good views of the apron and runway with some telescopes provided.
there is another feed on this site
Here that may be worth a read and a promotional video
on you tube hereenjoy your time in the v-room and your trip.
