Most do shut at Christmas but ask them about payment breaks through year - I can take two weeks off without paying in one school year.
Also how flexible are they about booking the odd extra day - mine will always try and fit you in and if I have to miss one session they will let me book another session in the same calender month (within reason)
You'll have to provide nappies, cream, wipes etc but worth checking
Make sure you check sleeping arrangements as well - is it a seperate room or just an area within the main room
Lastly and unfortunately ask about the security - every door locked at mine and double locked doors to get in - also have to provide photos of anyone who may pick up and password system as a double check
Hope this helps
