I am in the same boat as you, although my work schedule does not sound nearly as demanding as yours! I'm so sorry you are so stressed before your vacay!

The hubs and I own our own (mostly) online business, and in the past we have tried doing the dual working-while-on-vacation thing, and we found our very quickly that is NOT for us! We ended up just being stressed and cranky while on vacay, and that's NO fun! On our past couple of DLR and WDW trips, we have closed our business from the time we leave until we get back, and only take care of the orders we already have going on, but this too, also leads to working while on vacation, even if it is less than before. So THIS year, (we leave next Tuesday for WDW! yay!) we stopped taking new orders a week ago to give us plenty of time to (hopefully!) take care of all our customers and other work things BEFORE we leave, and then our vacation (fingers crossed!) should actually be a REAL vacation! No work allowed! My husband is not even going to check his email while we are away, but for my own peace of mind I think I am still going to.. otherwise, I would be worried I am missing something! It's one of those things... I'm SO thankful that since we own our own business, we can take our vacation pretty much whenever we want, but it's kind of impossible to ever FULLY unplug. At the end of the day, though, I'd rather work a little from my WDW hotel room than here at the office any day!
Since we are trying to get everything done before we leave next week, as you said, this has made for these past couple of weeks to be work overload at times, so I certainly feel you! Hang in there!! You'll be at the Happiest Place on Earth so soon!!!

Just keep swimming!! Maybe whistle while you work?

okay, I'll stop now!
