My wife always questions going with the Plus package so I put together a spreadsheet showing how many drinks/day is needed to break even. I was surprised with the results.
Assuming you pay your gratuity, get wifi internet, utilize casual dining, Ocean now delivery, and Medallion shipping, you only need to drink less than 3 drinks a day to break even. We typically have a coffee in the IC, a martini before dinner, and beer or wine at dinner. The Plus package is a no brainer for us.
