Would really encourage you to pick up a STAR card today or tomorrow and ride the trolley this weekend.
A STAR card allows you to hop on/off the trolley all night (one night only). If you do not have a STAR card, it will cost $1.50 each time you board the trolley (exact change, no credit cards... and you cannot purchase a STAR card on board the trolley). The only way to transfer between the Downtown Night Trolley and the Riverside Avondale Night Trolley will be with a STAR card. Otherwise, you would have to pay $1.50 to board.
Free STAR cards are available at:
The restaurants of the Jacksonville Landing (Koja, Fionn MacCools, Bennys, Hooters, Chicago Pizza, Cinco De Mayo)
Marksjax
Champblins Uptown
Burrito Gallery
1904 Music Hall
The Hourglass Pub
The Volstead
Dos Gatos
Burro Bar
*Please note, STAR cards are not available at Indochine or Underbelly as the article (which was written by me) implies
Special note, there will be fireworks downtown along the riverfront Saturday night around 9:30pm. Great way to get there and back is by using the trolley.
Also, trolleys run until 2am however it is highly suggested to board your final trolley well before 1:30am.
