You will usually get your tickets, etc... from them about 21 days before your trip. Last time we got a package ours did not come until about 2 weeks before. Once it hits the 21 day mark you can call and ask them for the Fed Ex tracking number then you will know if they sent it or not. You can keep calling until they give you the number then you can track it online and know exactly when you will get it!
Remember, since it's coming Fed Ex someone will need to be home to sign for it! I always have it sent to my office since my DH and I are never home during the day!
