Do I provide transportation

I have a guest who lives in Westchester.
Se says that she wants to come but needs me to arrange transportation.
My mom said she could spend the night at her house but go home the next day so no one has to drive her home at 11:30 at night. She refused. (Someone would drive her home)

I mean I want her to come but I really dont have anyone to play cheauffer..

Are we under an obligation to provide transportation..I feel that if she cant get there she should decline..No?

no it is not your responsibility... it would be nice but then should we do it for everyone else

unless it is so important...to you

She is actually under 30.
