Nana,
there isn't really a good or bad role at wdw. Ok ok I lie, Matt and I have some great jobs, him in costume and me attractions. So we have tons of guest interaction,but both jobs have good and bad points.
You my dear will have to basically sit in a ticket booth. Its not so bad, you usually have another person with you. You're in the shade and a/c so thats great.
On the flip side you will be first contact with a lot of less knowledgeable people. Also you're stuck in your booth too.
Ticket collecting is greeter/maingate, so thats a whole other role. Thats all I really know of the role, but I hope that helps you out!
