When tipping is expected, Disney makes sure to let people know it with a little note (“We are often asked about gratuities...”) and a blank line to add it to a credit card payment. Tipping of VIP tour guides is genuinely not expected and optional, as no suggestion is made, and cash is the only option even though many people don’t carry cash these days. Our last VIP tour was at
Disneyland and was
$600 per hour for 7 hours and I tipped $200. Our guide seemed very happy to be getting a tip at all; I suspect that quite often they get nothing.
