How much Portuguese should I attempt to learn? Or, in Lisbon, will we be ok with English? I really look forward to meeting you!! It's going to be a blast!

You'll be fine here!! Portuguese people are usually good English speakers(hope you have that luck when grabbing a taxi to the hotel).
Yes, I was so happy to know I could finally meet you, it's gone to be a blast for sure!! :) Almost starting the countdown mode!!

Yes, countdown mode has begun for sure. My Dad and I were planning on using Uber, does that sound like a good idea?

Yes, it sounds! Uber is present in Portugal for a year or so, and I didn't have the chance to try it. I'm more familiar to taxi, but much likely you'll be better on a Uber.
