I was gold member and currently enroll in platinum challenge (Feb 1 to April 30). So far had 16 nights already but no other business travel planned for the rest of this month. Thinking about book two more nights myself to get the status. My question is if I will be able to keep platinum for rest of this year and whole next year? Or it is rest of this year only. I think I won't be able to make 75 nights keep platinum status next year. So if it is only for rest of this year, it is probably not worth booking two more night on my own budget.

Any help would be appreciated
