We used the executive lounge at Montego Bay Jamaica the last time we were there, and they had shower facilities. We didn't use them, but I can definitely see where that would be very nice to have! The lounge there cost quite a bit more than Souliga, but they had quite a bit more services also. Having a spa place, where one can get a shower and maybe even a quick massage, now THAT would be a great thing to have at the departure lounge, instead of all that shopping, which hardly anyone one uses, other than a quick souvenier or some liquor..
