We would be taking the greyhound and going to a game at miller park plus looking for other things to do we don't drive is there a shuttle?

The hotel should be able to tell you if there's a shuttle. As far as other things to do in the area there may be some apps you can download to see what else is going on.

There is city bus lines & plenty of Uber/Lyft

Im not sure if there is a shuttle. But the hotel can give you a definate answer on that. Sorry

Yes

Yes. I commuted by uber/lyft

If you want an accurate answer, you should call the hotel directly and ask them
