OK, I have a few minutes and I'm at my computer instead of on my phone:
1) Do the Duck Tours, fun and entertaining and you see a lot of the city.
2) Duqesne Incline. Avoid it. Requires exact change that forced me to use a change machine on a $20 bill. It's hot as fuck in the cars and almost nothing to do at the top. The only redeeming quality is the view from the top of the mountain.
3) If you book far enough in advance, stay in the Sheraton at Station Square. Lots to do right there and it's quick access to the rest of the city. We stayed north of the city this time which wasn't bad either and probably cheaper.
4) I would like to see a Pirates game but we didn't (they were out of town). ESPN rated it the best park to see a game in because no one is more than 88 feet from the field and it's just a nice park in general.
5) Pointe Park (I think that's the name). Park at the Three Rivers that is beautiful and has a 150 ft. water fountain down next to the water.
6) PPG Place (a series of buildings that looks like a castle made of black ice
images). Very cool and there is a nice water fountain thing that turns into an ice rink in the winter. Right next to there is an open plaza with a bunch of restaurants. My brother recommends Permanti Bros. for some good food. I haven't eaten there personally.
7) Frick park was pretty cool but probably not so much without small kids.
8) We went to the Phipps Conservatory and Botanical Garden. It was mediocre. Probably better than Cleveland's, but certainly no Longwood. Some of the areas were closed because of a wedding. That sucked.
I think that's probably about it.
