How late into your pregnancy did you travel, and how far?

My midwife mentioned today that they don't recommend going more than an hour from home after 36 weeks. I was planning on going about 1.5 hours *without traffic* away July 4th weekend, when I will be 36 and a half weeks. We plan to travel during off hours, but the biggest risk is that I'd go into labor and have a 2 hour or more drive back, or have the baby at a hospital out there. We plan to play it by ear and see how things are at my 36 week appt, but we'll probably still go (the midwife did not seem appalled by this. She just said she couldn't recommend it).
