Tentative Travel

We could be leaving in 4 weeks!!!!! I'm about ready to officially freak out. We received an email on Friday with 3 tentative travel dates: 1) 9/5 - 9/16 or 2) 9/8 - 9/26 or 3) 10/5 - 10/16. The first 2 dates depend on when our travel approval arrives and if we can get a consulate appt (CA) on the requested days. There's still so much to do and I can hardly believe that after all this waiting it's now happening so quickly. Absolutely Amazing!!!!
