Welcome to Insiders oosch. Your access to the CL is based upon you either having Gold or Platinum status which you do, or if not you have a room on the Concierge Level. Has nothing to do with what site you book your room from however; that being said the site you book from may very well have an impact on you getting credit and/or points toward Elite status.
And don't be a one poster and done Insider, we want and need new blood around here for the long haul.
The closest analog to this question that I have had is this: we took a Collette Vacations tour through MVCI. One of the hotels on the tour was the Lisbon Marriott. Because the tour group booked the rooms, I was pretty sure that I would not get credit for the stay. But when we checked in, I told them at the front desk that we were Platinum Elite, and they immediately gave us access to the Concierge Lounge, and free WiFi (which otherwise would have been exorbitant). So the answer really should be "yes," although it is possible that it is discretionary with the hotel.
What did you actually say? Us here in Texas do not use those words nor have any clue how to find out what they actually mean. So I will try to translate for a few others here who live in neighboring states and Georgia (foxglove, SeaTexan).
If you give your Rewards number to the front desk you might get access to the CL as well as WiFi. Not so sure about the credit for nights/points.
How'd I do?
Welcome to Marriott Rewards Insiders, @oosch! So happy to have you join out community. You've come to the right place to ask property and Rewards specific questions such as the one you posed here. This is also a great place to share stories, tips, insights and all things travel!
In regards to you question, I'm doing some digging into the answer and will let you know once I learn more!
Thanks for posting!
Hi oosch! Welcome! lindseyh took a deeper look for you and was able to find out that while you won't be earning Marriott Rewards credit for the room, you are still entitled to Elite benefits. This means you will still have access to the lounge. Hopefully this has provided clarity, but please do not hesitate to ask any additional questions.
Hi oosch (and other fellow Insiders) - I know from your post that you have a credit, but if you use Hotels.com or some of the other websites, you may want to keep in mind that Marriott has the "Look No Further" rate guarantee. If you book a room at a Marriott property, and then, within 24 hours find a site at the property for a lower amount, you can call in to Marriott, and, upon verification (you should give them the URL address of the lower price offer) they will adjust your price, and take, if memory serves, an additional 25% off.
