The airport in Orlando is a very big, international airport. You are not able to walk anywhere from there unless you like walking along the highway. And even then it will take you about an hour to walk to the nearest hotel. To me, it seems like a big hassle to check into one hotel, try to fish out what you need for the night and the next day, pack up it back up and then finally get to your hotel. Most hotel check in times are later in the afternoon, but hopefully they let you check in early and have your room ready. Otherwise you will have to store your bags and then come back after your day at the parks to check in and unpack, etc. I would just check in to your hotel when you arrive in Orlando. You will be checked in and settled without the extra hassle. You can wake up, get ready and start your vacation. It might cost a bit more but at my age(47), I am willing to pay a bit more to not have that kind of hassle. I have worked my butt off and don't need to do that anymore.
