Preventative maintenance is most important and getting the batteries checked would be a very good idea before your vacation. As previously stated batteries are not meant to last forever. Also, as previously stated doing small dosages of battery recharging at the park is not really a good idea. Yes, in an emergency, it's a good idea, but it's not meant to happen all the time. Besides, you really don't get that much juice from recharging for a short time, here and there. It's not a total recharge. Make sure you take phone numbers for some rental scooter vendors. Some of them sell scooters and will have a limited supply of new batteries and they can do repairs. I still would want a perfect scooter before I leave home; because, spending vacation time to take care of problems is not a fun thing. If the worse happens then you can rent on the spot from a scooter rental. Disney rents, too in the parks, but it's very expensive. Make sure you know how to manually move your scooter if it runs out of juice. There is a lever you move that will make the scooter much easier to push and move if need be. I would go to the local zoo or museum or somewhere similar with your mom for a trial run to see how long her battery will last for a day. I think this will give you a good idea on how long the batteries will last at Disney. If you are only getting say 4 hours of use before needing recharging it may be time to get new batteries. You should be able to get about 7 to 8 hours with good batteries. Watch the gauge on the scooter to see how fast the battery energy goes down. This doesn't mean you can't still use the older batteries, but I would use them around the house for short trips, not a vacation. Getting back to the original question usually you can find outlets near restrooms. I feel it's easier to find outlets near restrooms that are in the inside pavilions. If you are going to top off the batteries it's best to do it at meal times. Show times are also good; because, you will be sitting for 20 to 30 minutes for them. Conserving battery energy is important. When you're watching a show, seeing a parade or fireworks you should turn the scooter off. If you wait in any long lines I would turn the scooter on and off depending how long you wait until you move up in line. Scooters are treated as wheelchairs and you are allowed to use the handicap areas for viewing the parades and fireworks with them.
