Sita  runs a bus service on the Salerno- Maiori-Amalfi line, and a direct service to Naples. It also runs a seasonal service from Naples Capodichino airport to Salerno. Alternatively, one can take a boat  from Naples to Amalfi and then a Sita bus.
The local SITA bus company run buses all over the Amalfi Coast with excellent connections to Amalfi, Ravello, Positano, Salerno and Sorrento. However for Positano and Sorrento, you will have to get off and change buses in Amalfi, which is the main SITA hub on the coast. http://www.sitabus.it Tickets cannot be purchased on board; they can be bought at Gino's Bar Sirena and at Bar Oriente, both on the lungomare
Coop Sant'Andrea are the major ferry company servicing the coast and operate summer ferry services to Maiori from Salerno, Minori and Amalfi. Visit http://www.coopsantandrea.com Metro' del mare  also operate a ferry service along the Amalfi Coast.
Renting a scooter is the best way to get round. However, only experienced motorcycle riders should rent one: do not rent one otherwise, as the roads are narrow and can be very dangerous for inexperienced riders. European A (motorcycle) lycences are of course recognized. If you don't have a European licence and/or a car licence only, check with your local Italian consulate. Italian B (car) licences entitle you to ride scooters up to 125cc, but not all foreign ones do. Also bear in mind that parking is not free of charge in most towns along the coast, and that scooters will soon be towed away if parked inappropriately.
Maiori is laid out as the letter L. There is a road and a promenade along the beach. Perpendicular to the beach is the wide pedestrian street, Corso Regina with stores, bars restaurants, and sometimes a market at night.
The Corsa Reginna and the 'lungomare Amendola' (the street along the sea) are the main streets of the town and therefore the main locations for shopping. Ceramics and limoncello (a lemon liquer) are among the most renowned local specialties. An excellent ceramic store is based at the end of the lungomare, opposite the Nettuno restaurant.
For all the young and hip, Maiori has a huge festival for the Santa Maria on the 15th of August.
Further details can be found on the official website of the local tourist office 
All the private beach strips have a bar where you can have a drink or you can take it to your parasol. Go to Bar Pineta in the Corsa Reginna you will never find a better place to eat and drink and is very relaxing. You could also order some Limoncello, Maiori is rumored to produces some of the best avilable.
