Not to pile on (you said you didn't think much about it, so no problem), but even if other teams wouldn't lend their facilities, the Glazers own an NFL team with top of the line facilities that is just a couple of hundred miles away from Miami (4 hours by car, probably an hour and half in that Lamborghini that Pogs was driving around in, and less than an hour by plane).
Also, teams lend their facilities to soccer/football teams all the time when they are in the US on these tours. In fact, the owner of the Miami Dolphins owns the International Champions Cup that we have participated in the last 3 years, and which they'll definitely want us to participate in during future pre-seasons. With the draw that we are for that tournament, especially after the mess in China, I think he would bend over backwards to help us.
