I asked this question of a bunch of cocktail connoisseurs on a drink forum, and was essentially told that if they had a newbie trying to make something like a pina colada in a hotel room, they'd run to the nearest nightclub. I've cleaned and loaded guns in hotel rooms, which I would think has much more danger potential than mixing juice and rum. I've also repaired leaky toilets in hotel rooms, which has the potential for flooding. I've done all sorts of complicated things in hotel and motel rooms. I think these folks are a little over the top.
Anywho, I bought some Barcardi rum, some Finest Call mix, a couple of Hurricane glasses, and some little umbrellas. I'll get the ice and pineapple wedges right before making the drinks. Worst that can happen is that it will taste okay but not great.
Thanks for the suggestions, the reminiscences, and the Latin.
