After months of making headlines, the Encore Boston Harbor resort casino is set to open on Sunday. And among the many choices patrons have to make — there are 15 dining options, including a Dunkin’ — is how to get there.

There are a variety of transportation options, and officials are urging visitors to use alternatives to driving.

“I think we are all one voice when we tell visitors to please leave your cars at home,” Everett Mayor Carlo DeMaria Jr. said at a recent press conference. “With all of these options, there is no reason to drive here.”

If you must drive to the casino, there’s indoor parking available. It costs $22 for six hours, or $42 for 24 hours. There’s also valet parking — $29 for up to six hours, $49 for up to 24 hours. Nearby, the casino has a couple of off-site lots – a 700-space community lot across the street at 31 Mystic St. in Everett, the cost is to be determined, and the Rivergreen lot at 1 Rivergreen Drive in Everett — no cost for up to the first six hours and $5 for six to 24 hours; one of the casino’s shuttles runs for free to this lot.

Here are all of the other ways to get to the casino, whether it’s by rail, road, or water:

From within Boston:

• Take the Orange Line to the Wellington or Malden Center stops and then board the casino’s free shuttle. Visitors can also get off at Sullivan Station and then use bus routes 104, 105, or 109 to get to the casino.
• Take the Silver Line SL3 to Chelsea. A free shuttle will pick people up at the casino’s own bus stop next to Market Basket.
• Take the Blue Line from Wonderland and get off at the Aquarium stop. Encore has a ferry from Long Wharf. There’s also a ferry from the World Trade Center to the casino. They both cost $7 one-way. Passengers can also ride the ferry from the World Trade Center to Long Wharf, which costs $5.
• By bicycle, the casino says it has “ample bicycle parking,” as well as a BlueBikes dock.

Merrimack Valley:

• The Amtrak Downeaster runs to North Station. There, Encore’s transportation guide suggests taking the Orange Line to the Wellington stop. A free shuttle picks guests up there.
• By commuter rail, take the Lowell or Haverhill lines into Malden Station to pick up the Orange Line to the Wellington stop, where the free shuttle awaits.

North Shore:

• Take the Newburyport commuter rail line to Chelsea Station. From there, walk ½ mile to Encore’s shuttle bus stop in Chelsea next to the Market Basket.

South of Boston and Cape Cod:

• The casino is offering a “Rockland Premium Motor Coach,” one of three regional shuttles from Park and Ride locations, the guide says — it costs $14 for a round trip.
• The casino also suggests taking the commuter rail to the Orange Line to pick up the free shuttle — or driving to Quincy to pick up the Orange Line.
