This is my first time booking a room on my own without my parents (first solo vacation), when you go and reserve your room, can you just reserve it, or do you have to make any kind of payment immediately? I know my dates, and I'm planning right now, I could make a payment of a few hundred dollars off the bat if I have to, but wouldn't be able to pay in full right away, the rooms I'm looking at (AoA Lion King or POR Royal Room) will probably book fast, if my trip is April 2017, how early should I worry about booking? TIA
