Just got back from a quick 4-day trip to Manhattan. My 10 year old son is a huge Harry Potter fan (he's read the books at least 3 times, some of them more, first time through was as a 2nd grader). For Christmas he wanted to see Harry Potter and The Cursed Child on Broadway. We heard they were releasing a block of tickets for this summer back in November. We were able to get 3 good seats for the shows (plural, it's a two-part show) for the first week of summer vacation. Then we booked a hotel a couple blocks from the theater, and a flight to LGA from Maine. He was super excited. Plus it was his first trip to NYC (he's only driven through the city before). On the extra days we visited the Tenement Museum -- which I found very interesting and especially relevant given the current anti-immigrant climate, Liberty Island/Ellis Island, The MET, and did some other touristy things like walk around Times Square, Central Park, Macy's, Stonewall Inn/Stonewall National Monument, and the One World Trade Center observatory. I would definitely do some of the other Tenement Museum tours next time I visit the city.
Anyway, I had never read Harry Potter or watched any of the movies, so about a month before the show I read through the books. I have to say I really enjoyed the show.
Now we're trying to decide on an international trip for our next major vacation 6-12 months from now (considering Iceland, Norway, and Patagonia National Park in Chile so any recommendations would be great), but I'm also considering squeezing in a trip to Bulgaria later this summer to visit a co-worker (he is in the states now but is probably going to have to work remotely from Bulgaria for a few months to give our employer longer to get his greencard squared away -- right now he has an H-1B visa that's about to expire). Bulgaria would be pretty low cost and we'd have a local tour guide. His family also owns a bunch of vacation rentals on the Black Sea too.
