Cruisin' Spartan

Thanks so much for the advice thus far. This is exactly why I thought I would post here. We've done several cruises in the past, but this is our first with a WDW trip on the front end, plus our first with DCL, AND our first with young kids.

One question regarding the private services though. If I was to go that route, how would we handle our luggage and getting it onboard the ship? We don't have to haul it that whole way do we?

I was hoping for some advice from the knowledgeable, experienced folks here. My parents (mom,stepdad), my family (Me,DW,DS [3], & DD [1]), and my brother's family (Bro,DW,DD [2]) are all booked on a trip to Disney World from Oct. 29-Nov. 2, then on the Dream 4 night sailing Nov. 2. I know we can get the Disney's Magical Express to our resort when we initially come in, but I need help figuring out transportation from our Disney World Resort to Port Canaveral for our Cruise portion (and back to MCO after the cruise). If I'm not mistaken, we can book transportation via bus from WDW Resorts to the cruise terminal as one option. I've contacted our travel agent for a price on this. However, I am wondering what other options we have.

Having kids with us ages 3,2, & 1 means we'd need carseats for any smaller vehicle transportation like a rental van or shuttle van. This seems less than ideal, and a considerable hassle if we can avoid it. We are already worried about dealing with a large double stroller that we're bringing for Disney (not that I don't appreciate advice about the stroller, but for argument's sake let's just assume that it isn't negotiable and it is definitely coming), so more large child carrying contraptions are not something we are super excited about.

Are there any other good options out there, or should we definitely plan on booking Disney buses to Port Canaveral from WDW, then back to MCO?

TIA!
