I have applied a single TSU to 4 consecutive 1 night stays spanning different room categories.

I called the concierge line and they took care of it for me.

this was a case where the base points rooms available were different and I couldn’t make a single award res for the 4 nights.
Example: first night: 2 queen room. Second night: king room. Third night: 2 queen room ADA. Forth night: 2 queen room.

base suite available all 4 nights and they had the property merge or combine the the stays in their system and blocked the suite.

note. The app still showed the single one night reservations.
