Disneyland.com is a good place to buy Disneyland tickets, you can also buy them at the kiosks in front of the gates at the Disneyland Resort.
Adventure Island is not free. You have to buy Disneyland park hopper tickets, then it free. If you buy Disneyland tickets you can only choose one theme park and stay there for the rest of the day.
Yes I would but I can't afford it.
Yes
No. One Disneyland ticket is access to EVERYTHING inside the resort.
You can buy it from Disney store in Disneyland or if there is a Disney store near you there is where you can buy it
The disney shop or Disneyworld/Disneyland
yes
Tokyo Disneyland sell them, if you ever happen to be there.....
Outside of the exclusive Club 33, you cannot buy alcoholic beverages at Disneyland. You CAN buy beer, wine, and cocktails in Disney's California Adventure.Other things you can't buy at Disneyland include selfie sticks and gum. I'm PRETTY sure cigarettes are no longer sold in the park itself, though since I don't smoke and have therefore never bothered to try to search them out I'm not certain of that.
It is much better to buy tickets online. You are guaranteed to be charged about fifty dollars more at the gate.
There are many different maps of Disneyland that showcase all of its wonderful attractions, but this is the one I prefer myself: http://disneyland.disney.go.com/maps/
Buy an advance ticket. WHy? Because do you REALLY wanna stand on the gate line?
