Med4Bike,
I'll be cruising Crystal for the first time in August on the Harmony. Do you need to carry cash around to tip if someone brings you a soft drink at the pool while you are on the deck? Do they not leave soft drinks with bowls of ice for self-service in the lounges? I think the whole tipping thing is going to really cheapen the experience of cruising but I hope not. Did you find it intrusive and onerous?
