I'll be doing a solo trip in late April using an ECV. Reserved the scooter today through Buena Vista Scooters. This will be my 1st time using an off-site provider. I went ahead and booked some accessories for the scooter, so the price is about the same as a standard ECV at the parks. I asked for a sun shade, a cup holder, and a cane holder. The sun shade will make the over-all height of the ECV taller, so I'm hoping I'll be a bit more visible (especially if I add some LED lights).

One tip that I did read was to not try to leave with the horde after the Fireworks. Either leave just before they start or wait out the crowd. It'll be much less stressful for you.

I'm planning on posting a trip report afterwards, so hopefully it will be informative for others thinking of using an ECV and especially if they are doing it solo.
