The porters are definitely worth $3-5 a bag, if the customs line is long. Usually they will open up a dedicated customs line for porters and airline staff/VIPs, and this will save you tons of time. I always just check the customs line and if there are more than 20-30 people, I ask if the porters have a dedicated line and then have them take care of my bags. Can literally save over an hour's wait when it's all said and done. Then you have spare time to visit the lovely Hibiscus Cafe! LOL
