Conceirge services via a platinum card.

I noticed that as a platinum visa card holder through my bank, Navy Federal, that they have a conceirge service. You can go online or call them, for anything for like booking you up for hotels, airlines, rental cars, sports tickets, restaurants in any city ect... I have never used them, don't know if they will search the best options or cheapest options for you, but was wondering if anyone of you out there has this sort of conceirge service through your bank and if you have ever had the opportunity to take advantage of it? I suppose that could be a cool tool to use if you were strapped for a computer and on the run, and the greatest bargains not a priority.
Like if I wanted to go to Detroit and catch a Redwings game and needed a rental car, tickets, and then after the game, to set me up a a fancy restaurant with reservations, and a hotel room. Snap crackle and pop. Oh, here's the visa card number......by the way...dam! Need you to guide me to find a good pair of Tom McCan's, mine got damaged in the friggin airport x-ray machine. Snap to it CONCEIRGEEEE.
