Yes, there is Miller Lite at CSA, but it is only available from the bars (and not in your mini-bar). In addition, you can get Guiness at the Sports bar, and Red Stripe and Red Stripe light everywhere. Carib is also typically stocked in the mini-bar.
Yeah, I guess I am a self proclaimed beer snob. My apologies in advance.
CSA (and I suspect all Couples resorts) serve primarily draft Red Stripe and Red Stripe Light. When you get right down to it, light lagers are light lagers - relatively bland, very drinkable, a good "all day on the beach" beer. I suspect if you like Miller Lite you will like Red Strip Light just fine.
I think each of the resorts has a bar or two where you can get some different beer (actually, I think Miller Lite in a can might be one of them...along with Heineken, Guinness in a bottle I believe...maybe others). You just have to find out which bar they serve them.
When I am at Couples, I turn off my "beer snob filter" and go for mass quantities of Red Strip...again, a fine "all day on the beach" beer. Cheers!
I am a Miller Lite drinker. Thats the only beer I like, in the states. I went to the grocery store and got a six pack of Red Stripe to celebrate the booking for Feb 2012. Man, it didnt go down so well!!! But, when I am in Jamaica, the Red Stripe is the only beer I will drink. So, try it!! Give it a couple glasses. Maybe it will be your preferred beer at Couples.
Most of the bars at CSA had Miller Lite. It wasn't in abundance, so occasionally they ran out at some of the bars. The only other beer I drank was Red Stripe and Red Stripe Lite, but I can't remember if I saw anyone else drinking anything else. Red Stripe is the only one on tap.
