Often the assumption is that silver season is worthless. The reason usually given is that the yearly maintenance fees are the same as platinum season. That's a valid reason and is one of the disadvantages of the Marriott system. However, chances are that a silver season unit will cost a lot less than a platinum unit and that could offset a lot of the yearly maintenance cost of ownership.
Another frequent reason given is the weather is not very good at a lot of resorts during silver seasons. There's nothing you can do about the weather but traveling during the offseason often avoids crowds and can even result in lower prices. Sometimes you can even catch unexpectedly good weather during your stay. We are currently at Hilton Head Surfwatch which is silver season here. Last two days have been in the mid 70's. Went to Mrs. Wilkes Boarding House in Savannah for lunch. Got right in with only a few minutes wait. Same with the Sunset Grill last night. That's impossible during season.
Probably the last consideration is whether silver season is a good trader. I own a silver season unit at MGO but have never stayed there. The reason is that I have always traded MGO into a better situation. All in all I've found silver season to work to my advantage. If you can vacation in the offseasons you might want to consider buying silver but I wouldn't recommend it for everyone if you're not willing to use it. Some sellers are practically giving them away on the resale market. You won't be ROFRed by Marriott either. It's another way you can take advantage this really bad resale market.
