Have a great trip! I found it very easy to take a baby. A carrier worked well for us, keeping them fed and comfortable was key. Parent swap was awesome for us to do more rides with our older kids. And if all else fails, know when to stop and take a break. On our last trip, all the kids(when the baby was a toddler) were tired and grouchy after the first day, so it made the second day unbearable. On the third day went just stayed around the hotel that morning and it saved the rest of the trip.
