Nine days and thirty six shirts? Sounds good to me! Seriously, take advantage of the laundry service. I pack woolite for swimsuits, but I bring three tanks and 3 pairs of shorts for the gym, tops, for a total of 8 days at the gym. I don't work out the first or last day. I sweat like nobody's business. I refuse to do laundry or iron on vacation! Is he really going to want to wear double shirts while there? It's hot! The first time I went to Jamaica, I packed a months worth of clothes and shoes for a seven day trip. You guys are going to get there, and you will wear 1/4 of what you packed. However, we all must live and learn. Or, maybe he will use thirty six shirts and you will take out at least four pairs of shoes you thought you needed (but didn't) for the extra sunblock.
There is no unhappiness like the misery of sighting land (and work) again after a cheerful, careless voyage ~Mark Twain
