We were told 3-5 days. Then when the time came and I was booked in for EPU, it was only 2 days. I left DH to take care of it himself. Thankfully it didn't make any difference, but if you're concerned about it being too long, tonight is probably a good idea. I think it's something hard to plan when you often don't know when you're going in for epu until 48 hours beforehand.
