Transportation during the trip may include a ferry ride to reach Avalon or renting a golf cart to get around the island. The ferry ride typically takes one hour and costs around $74 per person round trip. Renting a golf cart costs about $50-$80 per hour.
If you have more time, consider taking a helicopter tour of the island or parasailing for a unique perspective. If you have less time, cut out the boat rental and have a beach day at Descanso Beach Club instead.
