L doesn't do sessions during vacations. She just doesn't know her schedule to be able to set a specific time. I did ask for a session during her maternity leave and she agreed. However, during her out-of-office times, she has allowed extra sessions. And during any type of leave, she offers me emails and now texts with the understanding to not have expectations around when she'll reply. Like emails she might not reply to until she gets back.
I'm sure L doesn't offer these things to all her clients. I feel special that she offers them to me.
