I'm in uncharted territory now. We have been renting island villas for many, many years. I always tip the housekeeper and the property manager, usually $100-$200 each, but the services that they provide are pretty limited.
We now have an upcoming "vacation of a lifetime" planned for our family of eleven. The villa that we rented for 8 nights comes with housekeeping plus a full-time chef and concierge. They will be waiting on our family pretty much non-stop, three meals a day.
Having never done anything like this before, I have no idea what would be normal and appropriate. Your insights would be much appreciated. Thank you!!!
