Yes it is!
Tickets can be purchased thru the City Pass. Make sure you have two different codes as their system won't process two entries off the same purchase code. This bit us this weekend when my wife bought 6 passes through Groupon. Everywhere else in town just scanned her code twice for the two of us. The ferris wheel ticket booth would not.
Yes
The Ferris wheel is open. Tickets are available on the navy pier website. There is a number to call as well if you want to double check.
I'm not sure. Sorry.
