An hour travel time shouldn't be a problem at all, unless your pregnancy is high risk. When I went into labor was at work on a Saturday evening (about 5 weeks early - initially wasn't sure that i had gone into labor). I took a cab from Central to home on the South side of the island, called husband, walked dogs (our helper was off) and then got into the car and went to hospital. No big deal. I know it is different for everyone, but I never had anyone waiting on me, or doing extra things for me, even during the last weeks of pregnancy and personally I wouldn't have wanted any extra attention unless I was medically unable to care for myself.
My doctor stressed that the more active I was, even in the last weeks, the stronger and more healthy I would stay (unless of course there were complications preventing activity). Also, a routine change (moving in with the in-laws) could be quite stressful towards the end of a pregnancy, unless you already know that you get on with them very well...
