We are staying CL for the first time soon. The CL suite cost the same as two non-CL rooms (which we need with growing kids--I am frugal and sad that we are at the end of sharing a double room), so cost was negligible.
This trip is a non-parks trip. We plan to enjoy the pool, resort hop, and shop and dine at DS. We tend to eat one large meal a day when we travel. So we will use the CL for breakfast and a light dinner, and drinks throughout the day. We will have a large lunch out at our fav restaurants outside the parks. Since we won't be in parks all day we should get great value for CL and break even.
My advice--map out your daily plan (especially dining and park times), identify whether you will actually have time to use the CL, and run the cost. If CL benefits you, then do not. If not, then spend the extra money in a great meal, activity, or souvenirs, or save it for the next Disney vacation!
