Philly Marathon Spectator Strategy

Hi all! I am running Philly this weekend (my first marathon!) and my sister is coming for support. Neither of us have been to Philly before so was wondering does anyone know of a good way for spectators to see the race and cheer on? There’s a link for the 2023 one but 1) wanted to see if that strategy is still valid and 2) if anyone has any other good spectator places. Thanks in advance!
