Oh wow, okay. I'll search "newbies." Two adults, a 5yo and 3yo girls. Thinking fantasy for BBB - either April or September. Don't mind pulling kids out of school so we're pretty flexible.
Sorry for the vagueness - I'll do more research and come back
No need to say sorry in any way we all started that way, it's a broad subject so you have to narrow it down, a Fantasy is one of four ships, it's one if the two new ones in fact the most recent to come into service.
First thing, work out your budget and how much you can or want to spend and see what rooms it gets you.
Do use a specialist
DCL, TA a lot give you on board credits, don't just go for the first you see but google it.
Fantasy is a fine ship I have been on her for 14 days, it normally goes Eastern and Western seven night cruise.
Photos in my blog below.
When choosing a room, it's (1) to your budget, (2) family size and bed needs, then (3) if that hasn't sorted it out think inside room, window view room or verandah, for a seven night if it's inside budget a verandah is great for sea days your own space, away from crowds room service on your deck, views in and out of port.
Look into if you want to go east or west Carribean see what ports you like.
