Please note that I am in no way suggesting you could of/would of found it in a search. There're too many "fuzzy" terms for you to get a hit. Only reason I remembered the thread was I had posted this question last year.
...Interesting to note that soc***** (our Marriott guru here) edited his post last month to delete his input...I wonder why that? There was nothing there but an affirming comment...curious. But hey, we love soc*****!
Oh, BTW, don't forget that in most locales, Residence Inn will buy your groceries for you. At times,t his has been a real lifesaver for me.
