You tip how you feel, everyone is different. We're modest tippers, but holiday 6-8 weeks a year (it adds up!) Top tip though....tip housekeeping a little every day. The maid (sometimes a guy) has a day off, if you tip big at the end it may not be your regular maid that picks it up. Boy, did we notice when our regular maid had the day off! We tend to tip the bar guys who actually listen to what we want (Malibu, not Coconut rum for example), waiters (if good service - every night this last trip) and personal things, like the guys at breakfast at Sea Flirt learned how to make English tea, in a pot! They were well looked after. We're English, we don't have a big tipping culture. We tip for that little bit extra. You'll find your way.
