Well, I had been dreading booking this but fortunately I was able to find something suitable for a 2-day stay within my travel plans that isn't outrageously expensive or marked up. Came out to a little shy of $800 for 2 nights in an expensive location where I probably wouldn't expect under $300 per night at any worthwhile property. I expect this will persistently be one of the most annoying credits to manage (StubHub was also terrible but at least after I set up a seller account I can consistently churn out over $100 in resale value with fairly little work from the $150 credit).
