This thread is so timely! The only downside of our visits to Conch Out are the frenzy of getting everything put away and getting to the airport on time at the conclusion of our visits. I have not found any magic answers for this, the curse of being an owner as opposed to the more carefree renter. However, here are a couple of things we do that have definitely made a difference in the departure stress levels.
(1) Keep a basic wardrobe of clothing and shoes in a locked owners' closet for use when you are there, along with a duplicate of all toiletries and bathroom goodies. Our goal was to have enough stashed so that we could go to the airport with our wallets. Then if you're still missing something, it is an opportunity to shop. Don't forget to keep duplicates of reading glasses and sunglasses, too.
(2) Ask local visitors to bring minimal food, as so much gets thrown out when we leave. We limit our visiting guests to one food item. It's also a hassle packing up all the leftover items for someone else to take home when they leave the house! Definitely eat out the night before leaving.
(3) Reconsider special things that are only out when owners are there, like special sheets and linens and various accessories. Is having such things out really worth the hassle of putting it all away, doing laundry, etc. when you could otherwise leave those chores to housekeeping? I bought so many special sheets and now make do with the basic linen pack!
(4) Plan a late afternoon or early evening departure, so that you can leave the cleanup and packing until your last day. Early departures are hell. Our flight yesterday left at 5 p.m., leaving us plenty of time to do everything on our last day there.
(5) Most importantly, do NOT have overnight houseguests on your last night at the beach. They are still on vacation, while you are wondering how you'll possibly get everything done in time to leave and still be courteous and conversational with the guests. Very stressful. I have become very strict about telling people they need to allow us the last day for privacy and preparing the house. I also schedule housekeeping for the day after we leave rather than the same day, so we are not stressing to get out so they can get in.
And in the end, it is all worth it, is it not?
