Does this mean you'll be driving to the Hilton MAD? That's another boatload of fun, even with a GPS. If going on the freeway, you have to switch lanes about 3 times in about a dozen seconds, and no GPS can sanely keep up with that, and if you miss of those lane switches, you're not longer going to the hotel or anywhere close. (Ie, the hotel is right next to a very complicated interchange.) There's another way to get to the hotel using a street interchange a few blocks away, but you have to somehow convince the GPS to use that out-of-the-way (but much simpler to navigate in real time) route.

And hopefully your Tom Tom is more up to date about what roads actually exist around the hotel. When I tried an alternate route to the freeway, it took on a road that led into a parking lot where there may have been an entrance ramp years before but it was clearly not there any more. (This was a few blocks from the hotel.)
