I'll be at Disneyland next June with my 73 year old parents. They get around just fine, but to lengthen their park time I don't want them walking any more than necessary. For that reason I booked our stay at the Candy Cane Inn. I know they will make good use of the shuttle but I'm not sure how it works and have some questions about it: Is it on time? At park opening/closing does it fill up? And if so, do those left behind have to wait 30 minutes for the next one? The shuttle is free, but I heard there is a tip basket. How often and how much should we tip? At both the hotel and at Disneyland, are there benches to sit on while waiting for the bus to leave or arrive? That's it. Thanks in advance for any help you can provide.
