I recently stayed at the Hyatt Place El Segundo. While the hotel is nice, rooms are ample and beds very comfortable, the problem is you have to call the shuttle to come and fetch you. And there seem to be some reception issues at LAX T4 so it was quite difficult to make the call with my own phone (I even had a US SIM card), and the Hyatt doesn't have any courtesy phone there. Even the guy manning the information/hoter bookings desk had never heard about the Hyatt Place (I guess they might have recently take over from other brand).
So in this case where the OP is in a tight schedule I would not reccomend this hotel.
