We are leaving on Friday for what's really our first trip with our 20 month old (we did a quick daytrip while renting a house back in May...but this is our first multi day Disney resort stay). We'll only be there Friday - Monday, so I was planning on keeping things simple, taking buses and Magical Express from the airport. We've never done ME so I was excited to experience it for the first time. Now I found a great car rental rate ($70 at Dollar with all fees included!) and am debating whether or not to take it and lug the carseat with us. WWYD? Will we save much time driving vs. taking buses, or is it pretty much a wash? We've been lots of times pre-DD but this is our first time with a toddler on our own. I'm so torn! Also...I'm 6 months pregnant. Minor details. Baby brain.
