So how can I convince the agent of Marriott when I leave the hotel that to ensure whoever posting my bill will using "Group Posting Tool" to handle that , other than that you might not get any nights.
And from the contract example from above, the hotel would only guarantee about receiving points or mile , but not the eligible nights, right?
I contact Ren and CY BKK 3 days ago by Marriott event website but receive none response, now I send directly to JW to check if any response.
