The Lynx 350 will take you from the Palm Parkway hotels to Disney Springs. Depending on which hotel you are at, you will have to cross Palm Parkway to get to the bus stop. Just wait for a break in the traffic and cross halfway to the median and then wait for a break in traffic and cross the rest of the way. Make sure to take small children by the hand or carry them.
Once at Disney Springs, you will walk around 8 minutes into Disney's Saratoga Springs Resort and catch the free bus from there to Animal Kingdom, Epcot, or Hollywood Studios. (For Magic Kingdom, see the next post.)
The easiest way is to pull up google maps and ask for walking directions to "The Springs at Disney's Saratoga Springs Resort & Spa" and it should take you to the bus stop. You basically walk from the Lynx 350 bus across the Strawberry Parking Lot at Disney Springs (You will pass all the Minnie Vans) to the Saratoga Springs Nature Trail. There will be a sign that says walkway to Saratoga Springs (or walkway to Disney Springs on the way back.) Once you enter Disney Springs, you will walk across a bridge, past all the golf carts, and then to the main entrance at the Springs. The bus stop is right past the pool.
Saratoga Springs is huge resort, and the bus has 5 different stops (The Grandstand, The Carousel, The Paddock, Congress Park and The Springs.) When you are going to the parks, the stop you get on at (The Springs) is the last stop so once you get on the bus you will be going straight to the park. However, on the way back, you will be getting off at the last stop, which is the 5th stop on the bus. While sometimes they announce the stops, they don't always so make sure to count the stops and get off at the 5th one.)
Obviously, when returning from the parks, you do everything backwards. You get on the Saratoga Springs bus at the park, get off at the Springs, walk back to Disney Springs, and get on the Lynx 350 bus back to your hotel.
Again, all Lynx buses are $2 per ride, but as I mentioned before, if you are going to use the Lynx bus every day, just buy a 7 day pass and it will be cheaper. You can get the 7 day pass in the Lynx Pawpass app.
