planning to go and get a wand, dunno which universal studios yet but how does it work? i heard there are the character wands such as buying ones that are of dumbledore, harry potter, etc but there are also the birthday/celtic tree calender wands? is it possible for me to just walk in and ask for a certain combination like "do you guys have silver lime w/ phoenix feather" or something like that? are interactive wands (the ones that include the map and cast spells) ONLY a certain type?

Trying to find out if you can buy a wand online from universal Hollywood. Have a niece going and wanna get her her wand since I don't think her parents will. They are only going to be there for a few hours and she loves all things potter. Her parents not so much. Wanted the one from Hollywood so it has the map. Worst case just get the one from Florida but figured I ask since I'm having a hard time finding the website for Hollywood.
