I expect my post will generate a lot of flames, but I've received flames before so its nothing new.
If you can't ride the bus, don't. If yu're elderly, disabled, have small children or a baby in a stroller, the bus is not for you. Don't get on the bus and expect the seated passengers to be polite and give up their seats. For all you know, they might need their seats just as much as you so. Don't count on being in a "protected category" that will generate you any special consideration. Get a taxi. Yes, taxis are expensive, just
budget for it. Believe me, you'll be happier.
Before the flames get too intense, let me explain that I am disabled. I have arthritis, walk with a cane, and have great difficulty getting up and down the bus steps (usually dh helps), and have very poor balance. I would be inviting disaster if I chose to stand on a bus. Once I took the bus at Disney, it was almost empty, as I was making my way to my seat the driver started abruptly without warning. I fell against the seat. My dh caught me or I would have been seriously injured. Since then I refuse to use the Disney bus system. And, yes, they do tend to slam on the brakes. So, I repeat, if you physically aren't able to stand on a bus, forget it. Even if there's seats available, you could have a mishap like I did.
We recently returned from a trip to Hawaii. There's an excellent bus system all around Oahu that's efficient and inexpensive, however, I wouldn't even consider it. What if the buses coming back were standing room only? Don't count on courtesy and kindness from your fellow man. We just took taxis everywhere. Expensive? Yes, but a rent car, gas, and parking aren't free, either, neither is a trip to the ER. Stop whining about how people "should" be courteous and give us their seats. Expect it not to happen, and plan to take care of yourself. I'd rather depend on my own pocketbook to provide me with safe transportation rather than the "kindness" of strangers. That's just my view of reality, take it or leave it!
