Boardwalk Ticketing is showing up on the ticket calculator as the best option. However, I've never heard of them, and in searching on them it looks like they were in business a brief time in 2016 and just reopened last week. Has anyone used them or know anything about them?
There are lots of threads here about them. I think some of the best info about the company is on this one: http://forum.touringplans.com/t/wdw-tickets-boardwalk-ticketing/24940
You can use the search tool (magnify glass icon?) and put in Boardwallk Txketing and find other threads.
Touring Plans checks all the companies listed in the calculator.
