I think we are planning a December 2016 trip and am 99.99% sure we're going with POR, probably a Royal Room. I'd like to go ahead and book next week so we have a long time to pay on it, however we're expecting a new baby in January so obviously I don't know enough to add our little surprise to the reservation. If I go ahead and book with just the 3 of us, is it a huge pain to modify the reservation to 4 once the baby is born? Is that something I could do online or would I need to call and do it? I know it's super far in advance but I'm a Type A planner

We're debating between this resort and AKL. We've never stayed Deluxe and it's on my bucket list, but this resort just looks so calm and quiet and relaxing and my huband's two requirements are decent food options and a less crowded feeling so I really think this resort fits our needs. Plus we used to travel to New Orleans a lot and love the atmosphere.
Thanks!
