Scheduled c-section - when does it make sense for out of town parents to come?

Co

My parents live 9 hours away from me but I will be having a scheduled c-section so they plan to buy plane tickets ahead of time. They both still work so they can't take tons of time off. How long are we in the hospital after a c-section (assuming all is well) and in your experience does it make sense for my parents to come into town while I still have several days left to be in the hospital or should they schedule their visit for the day we go home? Thanks!
