I’ve read your updates so I know you’re reconsidering, but still adding my experience for reference!
I went into labour with DC1 at 39+3. No reason to think I’d have a baby before my due date, and obviously that’s not premature anyway, but it just happened. We were given a lift to hospital (25mins away) and that was enough for me, having to try and breathe through contractions as we wound through traffic and went over the occasional bump!
From leaving for hospital to baby being born was 12 hours. I had an overnight stay due to a minor haemorrhage and felt really out of it - combination of the haemorrhage, stitches, and generally just having birthed a little baby! However my birth wasn’t in any way considered particularly eventful, it was a spontaneous birth without needing intervention and nothing risky or scary. So basically even births considered straightforward aren’t always straightforward in the way we think they would be.
We had a 25 minute cab ride home in which the driver was lovely, went slowly and down back roads to avoid the bumps as it was all still delicate for me! I promptly spent about two weeks recovering, only popping out for some local appointments, mainly resting, taking painkillers, and adjusting to life with a child - feeding, night waking and so on.
So this overall fairly as expected experience of birth and postpartum recovery began at 39+3, and there is no way I would want to be doing any of that roughly an 8 hour drive away from home and my local hospital, in a hotel/B&B/holiday let, on a long drive in labour, or a long drive postpartum, and whatever other combination of possibilities... and I couldn’t even enjoy a holiday at 39 weeks for fear of it possibly happening.
Best wishes as you’re nearly there! But I wouldn’t take the risk
