Don't forget that if you pay cash, you are getting 10 HH per dollar plus 25% Gold plus 500 Amex booking plus 6-9 per dollar if you have the HH Amex.
That would offset the $50 diff. pretty much.
If you stay here, walk south on Light Street about 6-8 blocks to the Cross Street Market.
Old-fashioned city market with fresh everything (flowers, meat, fruit, vegetables, etc.).
At the W end is a sushi bar owned by a seafood wholesaler, so they get the best stuff. Possibly the best sushi on the East Coast. I never miss it when I am there. Also can get crab cakes, fresh-boiled shrimp, etc.
