Re: Indian Wells --- Seat Ticketing
Reserved seats in Stadiums 2 and 3 will also give you access to General Admission seating for all outer courts. Reserved seats in Stadium 1 give you GA access on all other courts. The only difference I see from previous years is that Stadium 1 can only be accessed with reserved tickets. Grounds pass might be your best bet, as you can visit all courts except Stadium 1 for $50 (or less for early rounds).
Keep in mind that it can be extremely hot. Stadium 3 is wide open and only has shaded seating later in the evening. Stadium 2 has some reserved areas that are in the shade all day, but those tickets get snapped up as soon as they go on sale. For shady GA areas, be prepared to wait in lines.
