I own at the Cove at Yarmouth and think it's a decent place. As mentioned, the units have limited kitchens and the refrigerators are very small. The resort is definitely clean and the units were refreshed over the last few years, so there are granite counter tops and newer appliances. I think that the big highlight for many families is the indoor pool. The timeshare was built as a resort, so there are tennis courts, outdoor/indoor pools, fitness center, and onsite activities.
You don't mention how many people are traveling, but if it's only two, then the place will work. More than 2, I would look to alternatives. If looking for an exchange and you have more than 2 in your party, I would recommend Brewster Green. I'm not sure if anything is available, but maybe. Brewster Green has more room, full kitchens, and washer/dryers in the units. Also a silver crown resort.
Also important thing you should be aware is that some units require going up stairs and there are no elevators. The townhouse units have a set of stairs in the units, but just to get to the townhouse units, involve a set of stairs. The other units (ground floor) I think are okay. For most this shouldn't be a big deal, but thought I would mention this. I think that the resort could help with your bags if there is an issue, but it's not the type of place that has bellhops just waiting to assist guests.
As a final thought, the resort is silver crown and I think the rating is fitting. It's definitely not gold crown, but it's a good resort in a central Cape Cod location. My family lives on the Cape and we've stayed here 3 times over the last five years. From the resort you're close to Barnstable and could do whale watching, ferries to the islands, shop in Hyannis. Drive to the Cape Cod national seashore, Provincetown, etc.
