Help!

MomX4
Supposed to go out of town tomorrow (3hrs away) went to get examed two days ago to be sure I could go. Dr said she would not recommend it. I was 1cm dilated, 50% effaced and she said baby's head is extremely low. Last night I started losing my mucus plug. For the last week I've had pressure and back pain. I still don't want to cancel our weekend getaway because we can't get a refund on the cabin! I hate to waste money. With my first I lost my mucus plug and went into labor a week later. This is my 3rd. What do you guys think?
