Well, to a point. However, depends too on how much two of you drink adult beverages. DH and I can typically consume enough adult beverages to cover the cost of CL. We are no lushes but we aren't driving so we do more than our usually 2 drink limit. LOL
Add in Disney's alcohol prices and it doesn't take long for the cost to add up.
Heck, last trip Lene handed me an entire bottle of the wine I was drinking to keep in the room

One trip she saw what beer we liked and stuck a 6 pack in our fridge while we were out.
So I agree the relaxation and time saved is well worth it but so is the added bonus of unlimited alcohol at hand.
