Congratulation!
Some words of advice. Don't do what I've done on my honeymoon. After a week in the Kisseemee areas (did the usual Disney / Universal Studio thing), headed down to Key West, rented a scooter and broke a leg. Our one month honeymoon turned into two month in Florida but at least we didn't have to wait in lines when we went back to the musement parks. 😛
I wasn't able to work anyway, so I thought it was best to at least suffer in style. THANK GOD + all the doctors in FL for all those wonderful pain killers that made it somewhat enjoyable. 🙂 At least the wife got to see all the parts of FL (Panama City, Talahassee, ST. AUGUSTINE ALLIGATOR FARM, Daytona, Miami, Ft.Lauderdale, Tampa, Orlando, Jacksonville, all the Florida Keys, FL Everglades and pretty much most part of FL states) that we initially didn't plan on which was great since it was her first time down there (she's originally from LA) but few hundreds times for myself.
To tell you the truth, I'm not a cheap person by any mean but personally, I believe the hotel accommodations could be the single largest waste of money on any vacations in Florida. Down there usually people enter the amusement parks when they open in the morning and stay to the time they closed, if they want to see/try most of the attractions as possible. Don't forget, you can't miss the last fireworks before parks'closing since it's one of the best attractions. By that time it's pretty late, then you would need to grab a bite to eat and don't necessarily spend all that much time in the hotels for which you had already paid a small fortune for. No matter what time of the year, you could find hotel accomodations down there contrary to popular belief and you wouldn't believe the differences in rates from places practically/literally accross the streets from one another.
I know while honeymooning you want it to be "special" but like anything else in life, it's what you make of it and the company you're with. Honestly, I believe 5 nights are going to be somewhat "short" and you two should be pretty occupied at all times. If you're going to spend most of the time down there (in FL - not her) locked in a hotel room then disregard all this BS.
If you're into all the finer things in life and have the right budget then Disney's hotel/lodging might just be the thing for you. Instead of renting a car, you pay higher premium toward the lodging and have easy access to all the Disney amusement parks by staying at one of their hotel resort. It's a kick to have Micky (or any of the other Disney characters) visit you at your suite during breakfast and people treating you like God. I don't recommend trying to hit on Miney either no matter how cute you think she looks. (but maybe not a good idea to spoil your wife so early into the marriage 😛) Last time I was staying at one of the resort there, the lodging alone was a little over a thousand a day but since the monorail is so close by, it made the trip to the parks just few blinks away. No need to rush or wake up early. Which would make it especially pleasant since the weather around that time would be very (VERY) humid to say the least. Did I say HUMID? I meant H-U-M-I-D!!!! (hope not for both your sakes) Don't forget to take your party clothes and hit the Paradise (I think) Island but don't let your eyes wonder or get caught while doing so. That would be bad.
