Yes.
HOWEVER...
You said PH (meaning Park Hopper.)
You do not need to buy the Hopper option on the 2-day tickets.
ALSO...
If you are staying for 4 nights, you could buy a 4-day or 5-day park ticket and THEN,
you would be able to book FP+ for all days of your current trip up to 60 days in advance.
Since you would be upgrading to AP, anyway, you might as well buy the multi-day tickets before your trip to get the advance FP+.
