Does he drink any spirits?
If he only has wine with lunch & dinner the House select would work
If he drinks more than 4 glasses or spirits then Prestige package would work
if he only has 1 or 2 drinks per day then pay as you go
There is always Happy hour 5-6 pm & 10:30 to 11:30 pm where it is 2 for one
Of course he could he could just buy some bottles of wine to take onboard ..drink in the cabin or pay the corkage fee to take to dinner/Lunch
You have to work out the best option for his needs/wants
