Thanks, I think that just makes a lot of sense. And, I have Priority Pass Lounge access, so I can spend some time there too.

No, it's not enough time. Allow a minimum of 4 hours.

Just wrapping this back up: I made amazing time, maybe about 90-120 minutes all in, from landing to going through security in the other terminal. However, I was glad I booked more time just in case, and I spent the bulk of it at some priority pass lounges. I'm glad I didn't do the train, as I wouldn't have known how to time that out either. Thanks for everyone's help.

Glad it worked out for you.
