We travel sometimes 3 times a year to Disney. I always mail packages down
On the planes we like to travel with our carryons. Since, the new rule of no shampoos & make up in our carryons, I have been mailing using FedEx Ground.
FedEx Ground is great for it's the ~cheaper than USPS~ & they will automatically insure your package with delivery conformation. Post office is extra money for the service. With Deliverly conformation, you can follow your package.
Last November, I FedEx Ground our package to the Disney Wonder & home to Jersey. It was there before my luggage. Last Feb, I FedEx our package to the Sheridan Vistana. It was there when I arrived also.
Word of caution, write all over, the outside of your package your name, resort address, & day of your arrival. INSIDE YOUR PACKAGE PUT YOUR "NAME & HOME ADDRESS" JUST IN CASE YOUR PACKAGE GETS LOST.
My friends & I sell on ebay, & mail out quite a bit of packages. FedEx ground has the best customer relations, they bend over backwards to help you with any problems. USPS, I am sorry to say, couldn't care less, whenever I had a problem.
This has been my experience, with shipping.
I am mailing out my box tomorrow to the Sheridan Vistana. My arrival date is on Saturday.
Hope this helps
