Hi! Nope, have never been to any type of Con before...just Star Wars Weekends. I think this is our hesitancy to buy tickets. We knew how to work the SWW crowds and shows but we know Celebration is a whole different experience.
This is totally different than SWW, I do both religiously, conventions and SWW, conventions have many many booths, open nearly the entire time the main areas are open... these booths can be from displays to people selling items.... In the case of a SW Celebration Convention displays can range from 501st huge SW display, to Roxy the Rancor type areas, and sets from SW that people have made, to things like Ranch Obi-wan had a large booth last year displaying a sample of what they have collected over the years, then even the company that made the R2D2 star wars planes announced them and had models at the convention. Then there are the vendors, from the star wars collectors that have figures dating way back to ones currently out there to big stores like Hallmark and Her Universe. The main areas are amazing.... and it does take a while to walk through it all...
In addition to the booths selling items there are many many artists there displaying their star wars creations for sale, and they are all open, all at the same time, instead of the schedule you had at SWW. And the art isn't limited to paper, canvas and sculptures, last year there was a huge tattoo area, where the best of the best SW Tattoo artists come in and people were even getting tattoos, and you could walk through the area, not too close but you could see their work and some of the people getting their tattoos!
I am also in agreement with
@P&L@WDW - the panels are not all long lines, some of the panels are easier to get into than others... Now Opening Ceremonies is crazy.... people camped out all night for that one... Big Celebrity panels are the ones that have hours wait.
I agree with
@P&L@WDW 4 day passes lets you see them all at your own pace...
