But this hasn't been too difficult. I also invested in some comfortable and WATERPROOF walking shoes. Curiously, I have noticed many Dubliners don't seem to mind wearing shoes which are clearly not waterproof. They know it's probably going to rain, but if they EVER want to wear their cute shoes they have to go ahead and wear them despite the rain.
As far as goes using the public transportation, at first I had to get used to some of the smaller details about using my Leap Card. These were ones mostly related to saving money, haha! For example, I now know how to save even more money by telling the bus driver where I'm getting off, so I'm not charged for the entire route when I tap my Leap Card to the box.
Getting used to the routes wasn't too terrible, either. Dublin is a large city, so you app-happy people will be happy to learn the Google Maps app works very well here. It even alerts me when my stop is getting close, and I can follow along as I pass stops on the map. (Again, since there's free wifi and free charging on all buses, it makes using the app all the easier.) Of course, I only used the app a lot in the beginning until I got used to the main routes and learned my way around from walking. I think it's important to note that most of the tips I learned about saving money and getting around more easily came from conversations I had with people. The Irish are very helpful and friendly. So apps are not THE answer, but they can be admittedly handy.
To sum up: 1) Public transportation, here, is grand because it can get you most anywhere while providing you with FREE wifi and charging. 2) Leap Cards are like magic, so don't lose them. 3) Appreciate your feet. 4) Don't let the rain stop you.
