If you have cost savings, you can compress the schedule by adding many resources to the tasks that was scheduled to be done during the time off.
In case of low risk, Execute the tasks in parallel (fast track the schedule)
You can have someone work in the morning during the holidays and another worker takes the afternoon shift. Another option: have one employee work Monday and Tuesday and another Wednesday, Thursday and Friday.

You can let the team working from home during the time offs.
You can offer a holiday pay differential to encourage the team work during holidays.
