Half and half. The ROI doesn't necessarily mean it has to be something you'd pay for. There are multiple ways to assess value. Meaning, if you had a choice in this raffle, do you v take the MSRP in the form of a prize or 20 cents per dollar of MSRP but cash.
How about take the cost that is being spent on the price? So, if for example the hotel costs a max of 880k MT points, and they have a market value of .5, that is $4400 (as opposed to $2000 x 5).
Similarly, for flights, if the flights can be bought for 150k AS x 4 and AS have a street value of 1.6, the flights have an apprx value of $9600.
Of course these are all rough, but my point is this is not worth anywhere near 40k. In antarctica, there was a true cost to the prize that was valuable even if you wouldnt pay that much for it. In this case, the actual cost of the prize is nowhere near full sticker since it is clear everything is being bought w points.
