Here's an example trip plan. You'll want to update it for addresses at your start location and FreepZ's location, of course.
Assume: 10.7 kWh Empulse, 3 kW charger, 120 Wh/mile @ 55 mph.
Ft. Pierce Nissan is about 55 miles north on US 1 (6.6 kWh, +1 kWh reaching US 1). If you can safely travel at 50-55 mph then that's probably doable on the Empulse 10, though I'm not sure how riding two-up may affect the energy consumption per mile. Melbourne, FL is about 38 miles further north, so you need at least 5 kWh plus some reserve to make it there safely. Call it 6 kWh.
Energy consumed: 6.6 kWh + ~1 kWh in Palm Beach. 1.5 hour charging: 4.5 kWh back, 7.6 kWh remaining.

Fort Pierce FL 34982
(772) 464-4645
Stop at FreepZ for the night (delicious electricity!). Should take around 6-8 hours to fully charge on 110V, but you'll be getting a good nights sleep then.
Energy consumed: 4.7 kWh + ~1 kWh in Melbourne. 8 hours charging: 8.8 kWh back, 10.7 kWh remaining.
Daytona Beach is about 86 miles away, that's just baaaarely inside the theoretical range of the Empulse at 55 mph. Stop off at Pat Fischer Nissan in Titusville. If they have two J1772 ports you can use then you can probably stop for an hour, grab food, stretch, get back on the road.
Energy Consumed: 4.7 kWh, 1 hour charging = 3 kWh back, 9 kWh remaining.

Titusville FL 32780

Daytona Beach is 51 miles away, you'll probably use around 6-6.5 kWh reaching there. Should not be a problem.
Energy Consumed: 6.5 kWh, 2.5 kWh remaining.
Total Energy Consumed: around 24.5 kWh to travel ~210 miles. 29-30 kWh at the wall.
The above are very rough figures. Definitely call ahead to make sure the Nissan chargers are accessible to the public - there are alternative "community" chargers available on plugshare if Nissan reserves their charges for Leafs, but the level of service there is a complete unknown.
In particular you may find that two-up riding is much higher consumption - possibly as high as 150 Wh/mile at 55 mph. Definitely test this and find out what YOUR consumption looks like before you start making hard plans.
Anyhow, I hope you two can make it on Empulses : ) If I come I will almost certainly be driving down (600 miles), but we'll see.
