Suggestions:
Make sure to drink plenty, plenty of water. Especially if you are nursing. Remember that your body is still healing.
Don't overdo it. If you feel like you need to stop STOP before you overtire yourself.
I honestly have never used a stroller for a child under a year old. Ive always worn the baby. If I was just taking a 2mo Id probably leave the stroller at home and take turns wearing the baby.
You don't need to bring the world into the parks with you. I see people with these HUGE diaper bags and wonder why

. I have 4 children, including one in diapers. I bring a small bag with some diapers, wipes and a clean outfit. Thats it. No reason to bring everything and its cousin with you.
This one some probably won't agree with but get an autograph book and take her around to see the characters. I have a book for my daughter with pictures of her at 2 1/2 weeks with all sorts of characters. Its so cute to look back on it and at 7 she is really interested to look at the book and have me tell her stories of when she was a baby. No she didn't care about it as an infant but its great for her now.
Make use of the baby centers.. They are great even for just stepping in and cooling off a bit if you get overheated or tired. One of my SILs bottlefed her child and would go in to feed him his bottle and give him a chance to cool off before carrying on with their day. Since I nursed I made use of the nursing rooms to cool off and drink some cold water. Straw cups aren't allowed (so nothing like a soda from the CS places) but water bottles are.
Clear it with your OB before you go, especially if you have any sort of issues with delivery.
A tip a friend shared, don't do your baby's vaccinations the day before you go on vacation. Crabby babies are never good to take on a trip.
Make sure you look up a number of a ped/urgent care clinic that takes your insurance before you get to Orlando. Sounds bad but if you do end up needing to take your child to see a doctor its good to know where to go ahead of time. Likelihood is you won't need this information but its always good to have on hand.
These are some of the tips. Mostly if you want to go make sure you put yourself and your baby first. Don't overdo it. If you husband wants to continue on don't push yourself just tell him you will met up with him later and go rest.
