Well, most of those people answering the phone have never been on a cruise, and don't seem able to just look up the answers on their employer's webpage:

Q: Are babysitters available onboard?

A: Babysitting is offered both in a group setting, and individually in your stateroom. In stateroom babysitting must be reserved through the Guest Relations Desk (Purser's Desk) at least 24 hours in advance.

It cannot be reserved prior to the cruise vacation and there is no guarantee that sitters will be available. The service is offered between 8:00 am and 2:00 am when personnel is available. Sitters will be assigned on a first come first served basis

Children MUST be at least 1 year old.

Approximate Rate: $10.00 per hour for one or two children within the same family or $15.00 per hour for three children within the same family.
Times and prices are subject to change without notice. Payment must be made in cash.
