Holiday

I and a few friends have booked a holiday for end of April I’ve tried to book time off work as my manager said to put it in as a holiday but I have no holiday hours left over is there a way I can maybe reserve it or let them know so that when my hours reset I’ll be able to have it off straight away I did ask if I could do my hours at the start of that week so I wouldn’t have to use holiday pay but they didn’t seem interested anyone had this before?
