Thanks Danny. We are a single week owner and never had an issue getting a place facing the beach until about 5 years ago when getting any reservation at all was close to impossible except however for late August. They put is in an oceanside this year and it simply irritated me both from the aspect of the hassle to get a reservation and not getting the unit type we bought. I think its a combination of preference for multiple week owners, Destinations, and their ownership of auctioned units that they then rent with the Ocean Front units deeming higher nightly rentals.
It is possible for Marriott to re-designate units but it requires amendments to be filed with the proper agencies, and it can only be done to the extent that it doesn't result at the time of re-designation in previously-sold inventory being over-sold. But it isn't something that comes up on TUG very often because it's hardly ever done by Marriott. IF they've done re-designations at Grande Ocean they should be able to provide you with the documentation. You could try contacting
customer.care@vacationclub.com - that's an email address which many TUGgers have used successfully. Or, you could contact
Executive Leadership. Be prepared for them to ask you to furnish them with a copy of the document that you've mentioned here.
But this thread shows that other long-time owners - one a founding owner - are reinforcing what the GM has explained to you (i.e. that all units in Sand Castle and Sea Horse have always been designated "oceanfront.") Their experience has to count for something, doesn't it?
Grande Ocean uses a placement system which is similar to other resorts on Hilton Head Island whereby owners are rotated among the "best" and "worst" units within the owned unit type, so as to give all owners an equal fair chance at being placed in the "best." If you were placed in a unit which is currently legally-designated as the view type you purchased, and MVW can demonstrate that in contrast to the document you're referencing, then you've been placed correctly. (And, you should have priority for a "best" placement during your next owner stay.)
If you own Oceanfront and were placed in a legally-designated Oceanside unit, that's completely unacceptable. IF that's the case, in your shoes I would be looking for compensation and I don't think it would be unreasonable to ask for a replacement Week the same as what you own.
Good luck if you take this further - I'm interested to hear what you learn, and I hope that MVW leaves you with a better understanding of your situation.
