The moped seems like a good mode of transportation. Few of the bikes i saw in front of the hotel seemed well maintained. Would not have wanted to be stuck in the countryside in a foreign country.
Might have been fine in the city.
My friends rented one for a few days and was happy he did, even though he had to work around it's non-starting quirks.
Most rental cars were near new units.
The most fun thing we did was rent mopeds, they are usually $9 for 2 hours and $22 for 24 hours (yes, you keep them overnight and ride all night long up and down the strip.....or not)....UPDATE FEBRUARY 2006...We rented the mopeds for the entire week and were able to get them for$100cuc, the usualu price is $140 for the week, or $20 per day
