The price for an all day ticket on the Old Town Trolley from keywest.com is $24.30. The Disney Tour is $24, but that's just for the 60 minute tour. I am not sure you get the on and off privileges with the Disney Tour. I don't want to misspeak, but it doesn't sound like it from the way it is described in the shore excursion booklet.
I have never been on this tour before, so I can't say I personally recommend it, only that I feel that buying my tickets beforehand, having the ability to tour at my leisure for the whole day, is far better than the one hour tour offered from Disney.
Here's some of what the web site says.

* Your eTicket is good for all day use from 9am, with the last re-boarding at 4:30pm. If you chose to stay on the trolley, the tour is approximately 90 minutes. You may "hop on" and "hop off" as many times as you like during the hours of operation.
Now, we are getting into port at about noon, and the ticket is good til 4:30 p.m., so, that isn't a really long time, but it still seems like a better deal than Disney. I'm just throwing it out there for all those who mentioned that they would rather do Key West on their own.
