Just finished a couple of months in the RI San Jose South. OK property, maybe a little tired, but not bad. (But I just came from an extended stay at a Four Points that was brand new, and in downtown Chicago, so the competion was strong.) The RI staff was very good, the bed was brand new, and the overall my experience was good. btw - I did not eat the breakfasts, co-workers that did have it were not impressed.
I've had good and bad experiences (the worst was in Cinncy, north of town, maybe in a suburb called Sharonville??). I think RI's tend to vary much more than the other Marriott brands, for that reason I'll stay away until I know that the location is good.
