Holiday Inn - All Inclusive Food/Beverage???

How are the drinks at the Holiday Inn for all inclusive? I read that they serve drinks in styrofoam cups (coffe cups)? Is there any glass poolside? Is it draft beer? What size is the average AI drink (say pina colada)? Does it include room service? Can we take the drinks back to our room?

Trying to decide whether or not to spend the extra $200 for 2 people AI for 5 days. It does include a dinner at what looks like a very nice restaurant. I figure we will spend at least a day and half lounging/drinking at the hotel and the one dinner.

Thanks in Advance

simple answer
whether we are in Puerto Vallarta, acapulco, cozumel it doesnèt matter
take a platic insulated cup (large) with a top
we all have them for coffee here in Canada
each time you go to the bar they will gladly fill it with beer or the drink of the day
When we leave , we always give he cups to the staff

the drink stays cold and no sand in your drink
real easy
