So I have made my final deposit, but did not pay for the ddp as I wasn't sure of my dates give or take a day and was told as long as I'm adding to my total I wouldn't pay a penalty. I was going to do that tomorrow, as our arrival date is the 28th, however we had a family emergency, and now I'm not even sure what the status of our vacation will be. Can I still add the ddp/make date changes up to 3 days prior arrival or 2 weeks without penalty, as I've heard both?
