Should he go?

So my husband has won a trip to Lisbon from a group activity at work. They were supposed to go sometime this month but his work place have booked it for the 5th - 8th Nov (3days). I'll be exactly 36 weeks pregnant then, due 3rd Dec (FTM). I told him that I would like him to finish taking all his trip by the end of this month so he can be around in the last 4 weeks just in case. He's been travelling a lot over the last few weeks so I have no problems with him going and I'm not upset about it at all. It's just that I'll be 36wks and there is a possibility of me going into labour early. So far, we've agreed that he can go because the docs see no complications, I'm low risk, everything's healthy and going good but I told him let's see how things go nearer the time. What do you think? Is it a good idea for him to go? I know it's only 3 days but it's so close to delivery.
