Gold Mobility is by far and above the best, they have the best battery life, the scooters are replaced every 6 months and they refurbish and , so they are always in great condition. They also offer some free extras that no other company that I know of offers, such as the under carriage lighting (it makes a huge difference in making you visible at night and helps light up the walkway), a cell phone holder, a fan, a cup holder (two on some models), on the Victory 10 models, the captains chair, which is something most other companies charge extra for and makes a huge difference in comfort, there are USB ports for charging your phone as well. They also add reflective strips to the scooters, which also help to keep you more visible and have fewer issues with people running into you. You also get 4 free ponchos and two shower caps. The shower caps are to help keep the tiller and basket dry in the rain.
They do offer a free additional accessory, but DH and I usually decline those, as they do make it more bulky and honestly while their sun shades are some of the less obtrusive ones, they still get annoying.
One thing to note is that at present they only have pickup and delivery between 7 AM and 7 PM, but if you somehow have an issue with the equipment (highly unlikely), they will help you any time. Most other companies like Buena Vista and
Scooter Bug used to stop at 7 or 8 PM and then didn't get in until 8 or 9 AM, I don't know if that has changed with the other companies or not though.
I personally prefer the in person drop off and pick up, then they can help me adjust everything for my comfort and when they pick it up, I know they have received the equipment. There have been problems in the past with Bell Services not being able to find the key and sometimes even claiming someone never returned the scooter.
Another note with Gold Mobility is they will meet you on your schedule, not a predefined schedule, for example Buena Vista only has two or three drop off and pick up times per resort. Gold Mobility isn't the only ones that pick up and drop off on your schedule, but they were one of the first and one of the only ones I know that are waiting for you to arrive rather than you waiting on them. Meaning, as you drive in or get off of Magical Express, your scooter is sitting there waiting for you, with the caveat of being between 7 AM and 7 PM and they are really good about working with you if you arrive early or late.
Additionally, according to their Facebook page they are now testing Victory 10s with two 50 Ah batteries, the standard batteries are 35 Ah each, so. this is a huge upgrade and something that none of the other vendors are doing to my knowledge. Even before this upgrade, their batteries generally lasted all day in the parks, with this upgrade they will do even better. They are also testing even better undercarriage lighting and a stronger fan. It sounds like they have a handful of them that they are randomly delivering at present for testing. They can't guarantee that you will get one of the new units at present, at least not until their entire fleet is upgraded, but this is an example of the thought and effort they put into their service.
In short, I know too late, there is a reason they have all 5 star reviews everywhere (at least last I checked), they really are that good.
