Glad you asked. We recently spent a week answering readers' questions and offering advice on onboard tipping. Plus, we polled readers and found out not only how they tip (prepay? Envelopes? Opt out completely?) but how much.
The result is The Ultimate Guide to Cruise Ship Tipping -- check it out, and join the conversation both on the Lido Deck blog, and in the comments section on the page.
