So our family was going to go on vacation for 28 days to Scotland and Iceland. I booked the tickets to Scotland, and from Iceland already.

Now, I have to go on a business trip that is supposed to start 5 days prior to our planned end of vacation. I guess sometimes planing in advance is not best. This business trip would be good for me and I do need to go. There is no question about that.

Our vacation tickets are, of course, non refundable. And now any other tickets in August are twice as much. There are a lot of issues to work out.

I wish I could just change all our tickets and just leave 5 days earlier, but I won't be allowed to, I'm pretty sure. I do not want to just lose the money for all 3 tickets. I will probably just have to buy my ticket ($500) and lose the money on the ticket I already bought, and miss out on 5 days of Iceland, leaving my husband and son there by themselves.

Also, my DH will need to take an important exam right after coming back, and will need to study for a weekend right after vacation and also to grade his student's finals. So we would need to make sure that my mom takes our son for the two weekends I will be away working. However, I don't yet want to ask her - because she will worry herself sick. She is just a "worrier" and imagines worst possible scenarios, so she will naturally ask where I am going and than will watch the news and drive herself crazy.
