There used to be a tram from the Disney hotels but that was stopped and guests must use the monorail or walk to the trams a long long way.
There is the Lion King tram which serves the parking lot south of DCA and stops at an opening in the fencing that leads to Harbor Boulevard. This is one of the two trams I mentioned. Disabled guests go up a ramp to a platform and wait for the tram. There are only so many tie downs for wheelchairs and require the bench seat being lifted. This is the front car and can mean a very cold ride and diesel fumes. Personally I rather have 5 guys haul me onto a rear car than smell the fumes but usually the ride is short. This is level ground.
The main Mickey and Friends parking garage area has the second parking area and trams. This is the one I was discribing. That has many loading zones and they can unload guests on the opposite side of the unloading zone. Guests in
ECVs and wheelchairs wait until the tram gets in a loading zone to unload. CMs are very nice and helpful. The tram area to the parking garage is downhill mostly and smooth, boy slip sliding smooth mosthly. Uphill when you are leaving.
The main entrance is off of Harbor and hotel guests can walk through that entrance to get to the park entrance. There is an area for shuttles from local hotels and a taxi stop. I recommend talking to your hotel about a shuttle. Taxis and shuttles get you only so close. Public transportation is located outside the park, long story but long ago they did enter the park.
If you are staying on the north west area then you would have to take a hotel shuttle, drive, take a taxi or walk blocks to get to the Mickey and Friends parking Garage then on to tram.
Another option is to have a taxi drop you off in the parking lot just north of Downtown Disney then walk around the Rainforest Cafe to the monorail. Drop off at
Disneyland Hotel and walk to the monorail.
If I knew which hotel you were at then I could help you more, sorry.
