Have recently started using the scooters in the parks but this will be our first trip using early EMH when I'll need to rent a scooter... I assume the scooter rentals at the front of the parks are open for early EMH, right? 2nd question...if we're there early and then leave for a mid-day break my understanding is that if we keep the paperwork, we can get a scooter again when we come back for the evening. My Question is...how often are they "out of scooters" when you come back at say 6:00 PM? We will be going the week before Mother's Day, so not a spectacularly busy time of the year, if that helps.
