Taking family to ( amazing and free! ) USA STEM Festival at DC convention center. Bid 5* down to 3.5*, incrementing bids starting $65 , and adding Downtown and Downtown White House along the way. After 2 more dead end sessions starting $75 ( last night) and $78 (this morning), started $106 up to $118 for 4.5 star with 3 zones. At $120 for 4 star, hit Marriott Marquis FTW. This is literally next door to convention center, and 9+ guest rating. ( There was a PRICELINE EXPRESS deal for Capitol Hilton 4*, 8.4rating for $123, but it came and went, and is 3/4 mile from convention center).
