The other frustrating thing about the busses is many people do not have courtesy any longer. I always give up my seat to the elderly and most women. I saw too many healthy adults remaining in their seats while grandmothers were standing. Guess it is just the way I was raised.
AMEN! I always give up my seat as well, especially for people with young children. My wife will as well. I saw a LOT of people unwilling to do so last year, and it
really bothers me when I see teenagers that won't give up their seat and their parents don't say a word. My son was 6 on our last trip, and I told him to get up a couple of times, to which he protested because as he said "those other big kids aren't standing up for anyone." I explained things to him on the bus, and he happily gave up his seat for anyone who needed it more than him afterward, even at 10pm on the way back to the hotel! One older lady expressed her gratitude and told my wife that we were raising a "fine young man." Don't think I've ever been more proud of him.

IIRC, he even said "you're welcome" without any prodding!
On our first trip, my wife held my son (5 years old at that time) on the entire trip back from MK to AKL as it was almost midnight and he was passed out. Yeah, we stood the entire bus ride while more than a few able bodied men sat comfortably in their seats. I think that's the only time I saw my wife really upset on any of our trips.
The only other thing that drives me crazy are the people with HUGE strollers (I'm not talking about umbrella strollers) that RUSH to get onto the bus first only to take the very front seats forcing everyone else to walk
over their gargantuan stroller that sticks out into the aisle. They're also first to get off the bus. I don't get it.
Never really had a bad experience with a CM. Had slow service at some restaurants, but only when things were super busy and super hectic. Can't really blame the CMs in that situation. Doesn't bother me. We're on vacation enjoying ourselves, and their working their tails off, so we try to stay pretty laid back. Never had any problems on rides with the CMs either. Some rude guests every now and then, but you'll run into that anywhere. I'm sure we've done something on accident that offended a few people as well. We're surely not perfect!
