I will echo the other posts. The 48-hour shoe-horn is a very good thing indeed.

The arrival gift is worth about $13 at a full service, and $2-$3 at any other MR property.

The real answer to your question requires an understanding of the opportunity cost. Since you are gold already, I assume this means diverting 25 convenient nights to MR instead of hilton, to get plat the subsequent year at 50 stays at MAR. If those are all full service, it is probably worth it.

If your MR stays are mainly courtyard or springhill, its worth less.
