I highly recommend a folding cane. While you can't take it on things like roller coasters (as said above, they will hold it for you), it's MUCH easier to deal with on other rides, in shows, in crowded restaurants etc. Just don't make the mistake of folding it up to go through security. My dad did that one time, and they thought he was trying to bring in nunchucks lol. But speaking of security, if you're able to walk through the metal detector and send the cane through (unfolded), it'll go faster. Otherwise, they'll wand you (not a huge delay, just an extra step).
