We tip servers and bartenders the same as in the states. 20%, maybe a little more in Jamaica. House keeping gets $5.00US daily and an extra $20 each week. Security gets $20 per week. Also little gifts for those with whom we have long time friendships. Along with your money, take time to get to know the staff and build friendships. Investing a little of your time with them reaps greater rewards long term than a bit of your pocket change!
