My husband's company has this policy where they all submit their first, and second choice dates for holidays at the same time. They look at everyone's requests, then allocate the holiday. After than, people can then book whatever.
The problem is, they don't do this until very late. They still haven't done this for next year, and I am a teacher and we have a daughter in school, and we were hoping to book our summer holiday ASAP to get a better deal.
They have said to my husband, they will ask people for dates in a few weeks, as it has to be in line with the rest of their company.
