For day 2 there is a direct bus back to POR so no need to worry. There should be a helpful transportation CM or security CM at the bus depot to point you in the right direction if you get lost. Easy direction is when you leave MK facing the lagoon the buses are on the far left.
Here now, and have been asking CM's about transportation as needed. Interesting responses. Was told very few buses run for our breakfast time and we were encouraged to take a taxi. Later when I asked if I was going the right direction for the monorail to the Polynesian the dude pointed both ways with an exasperated look. Couldn't just say "Yes?" So far it's been going ok, but we both definitely feel lost as first timers- and have not found cast members to be particularly jazzed on helping. It's more of a "duh, you don't know that?" reaction. (Not unlike some of the responses I got here early on) I had to ask the front desk for a map and apologize for not knowing where the bus stops were when I went to them for help with the breakfast question. If you've never been here, it's difficult to tell where things are and which way to go, etc.
By far the worst thing we've encountered so far are other guests. Even on public transit, there is little of the etiquette we've seen in other cities. One woman let her children run screaming around the Magic Express lines in the airport. Bumping, pushing, etc. are all things we're learning to look out for on our first day.
That said, there have been some really awesome people here too. Just really put off by the attitude and demeanor of some people and the behavior they deem acceptable. At Ghiradelli a lady literally stood next to our table and watched us eat. Sat down as soon as my husband got up, before I could even follow suit. Oh well.
The Magic Kingdom bus center is well labeled. The system going there seems efficient, even if the crowds don't appreciate it. A father in a family ahead of us was literally trying to wave buses over to stop, and then shaking his fist and insulting them when they did not. Even I could see there's a well-honed system there. Disappointing, and terrifying, to see the examples set by some of the parents.
By far the best transit experience has been the boat back from Disney Springs. Well labeled, efficient, super friendly staff.
At Trader Sam's tonight we got our check, paid, and then sat with the signed receipt for like ten minutes before my husband suggested maybe we were supposed to take it to the staff member at the entrance. I did so, asking "Excuse me, do I bring this to you, or should I wait for my server?" I was told to wait for our server. Twenty-five more minutes go by, with no check in from our server (who was very nice by the way) so I again go up to the front and explain, "She still hasn't been back yet. All we need is the souvenir glass and we can go." (There are people waiting for space at this point, and we were just wasting room). Turns out, we
were supposed to go to him. He gives us the glass and we go. He kind of apologizes, but it again seems like we should have known better somehow.
In short, The confusion I felt in planning has definitely carried over onto the property.
Despite this, we are still enjoying ourselves, and hopefully tomorrow we'll be even wiser.
