Updating here, everything turned out successful:

• I made 2 separate reservations, both in my time, for the dame dates and times, for 2 rooms total.
• The hotel charged my credit card twice for each room
• I had two folios and received two bills
• I paid for both rooms using a credit card in my name

Marriott posted the points for both rooms in a single transaction. Also, I received ambassador spend for both rooms. However, as expected, I only received elite nights for 1 room.
