Theres a shop next door to the hotel which sells alcohol or theres other shops just down the road, we bought bottles of vodka and baileys and drank on our balcony most nights after the bar closed. When we were there we didnt hear of any break ins but they do happen in all hotels unfortunately, theres always some people out there wanting to ruin things for others, such a shame.
If the beer is the cheapest you can buy it really didnt taste it to us lot, we preffered it to the normal san miguel actually, but everyone has their own taste.
Just 1 word of advice, dont go in the sauna then come out and drink several glasses of the lager, it really wasnt good, lets just say I didnt make it down for dinner that night

silly me didnt think about the sauna dehydrating me
One great thing I will suggest is you can pay a deposit at reception (which you get back) and you get a key to the roof, where you can take some drinks up, theres a mini fridge, a few sun loungers (good quality ones) a jacuzzi, shower and toilet,so you dont need to leave, could stay up there all day if you really wanted. its so peaceful and not many people know about it or bother with it. Theres some amazing views too! Oh well, might even see you up there Janet
