I like to tip porters $2 per bag. Because I want my luggage on the ship when it leaves. hehehe If it's my husband and I I tip $5 for the 2 of us. I jsut want them to know I appreciate them handling our bags. Hey we are all out there trying to make a living.
Room service I tip $2 per time. We usually jsut get juice and coffee in the morning. The rest of the tips are ok what they set to pay. i have tipped a head waiter quite well one time. He was so attentive to our group. Every night...He deserved the tip.
