The best advice I can give you is to consider the Cinque Terre train card (http://www.cinqueterre.eu.com/en/cinque-terre-card). Not only will this card give you access to the trains and buses between the 5 towns, but it also doubles as a permit for the trekking trails. Hiking between the towns is absolutely beautiful and very rewarding. Hope that helps! Enjoy your vacation.
