I signed for Platinum Challenge in July (expires on October 31) and completed 6 stays so far. I reviewed my possible hotel stays in the next year and so far I will have only 1 trip (5 night) where Marriott hotel (full service property) will be involved. I can make 3 stays (mattress run) and it will cost ~$250 in total, but now I don't really sure if it is worth to do (in terms of $$$). Is it really stupid to stop now? Another question - I know that Gold challenge is 6 stays, do you think I can ask Marriott to switch me from Platinum Challenge to Gold challenge, which means for me no more mattress run.
How many total nights have you stayed since you started your Plat challenge ?
