I spent 45 minutes on hold before booking mine. In my eagerness to book, I couldn't navigate the Costco travel phone system. They didn't open until 7 a.m. PT anyway. So, I booked on the regular
ABD line. I got the early booking discount PLUS a $100 per person loyalty disco!unt since we had gone on a trip this year. I called back on the Costco line and was able to add the $500 Costco cash card to the reservation. Woo Hoo!
