I'm sure the ritz is fantastic, but I just returned from there, and this time I didn't stay at a Marriott. Check out tripadvisor.com and look at the number 1 recomendation. It's a small boutique hotel, but well worth it in terms of location and staff. Highly recomended.
Sure, no point stays, so if that's important, nevermind. 150K Marriott points are worth $1500 - $2250 to me, and a 5 night stay in that hotel cost me about $1000, although I was in a small room (which was fine).
They were offering free incoming airport transportation, breakfast, free internet and afternoon light snacks. They even gave me a free dinner in their resturant (which was excellent) for one of the nights.
