Hi there,
Local buses is by far the cheapest way to
get around in Aruba offering many convenient stops so, I would recommend this way if you want to keep within a budget. Prices start at around $2 return tickets and make sure you have the right change before you board.
The buses run each half hour from Monday to Saturday 6 a.m. until 6 p.m. They also run on Sunday running each hour.
The routes are between San Nicholas and the resorts along the beach on the north-west coast with stops in
Oranjestad.
Hope this helps
