If you've got a rear rack on each bike and rear panniers, that should be plenty. Add a handlebar bag to each bike for the things you need to keep close to you. That's all you need. If you were planning a longer tour and one in more remote or harsher areas, I'd suggest front racks, but not for one week in Florida in the spring. You're not even taking sleeping bags.

Most of your list looks decent to me, but there are a few thought I should mention.

1. You don't need much in the way of clothing. There's nothing wrong with taking a bit of time along the way to do laundry. This means less clothing, which also means less bulk and less weight.

2. I don't see a lot of value in luggage locks on the tent door. If someone sees something of value inside, an honest person would not consider taking it and a dishonest person might slash a locked tent to get at your stuff. The locks, while light, seem useless.

3. If the droid phones are battery hogs, turn them off except when you absolutely need them. You're on vacation and you may want a break from some of the technology.

4. I haven't used the propane/butane fuel mix, so I don't know how much weight it will add. Is this stuff easily available where you're going? If so, you may wish to have just one canister at a time.

5. One item I don't see is rough weather clothing. I haven't been to Florida and I have no idea what you can expect for weather, so the clothing you need is not the same as what I'll need. Do you need a light rain jacket or waterproof pants?

6. I'm wondering why you are planning to take two battery chargers and 12 rechargeable batteries. On my last trip, I didn't use a battery charger. Before that, I've only needed it because I normally have a GPS on the bike. What are you taking that will demand battery power?
