Have stayed at the WorldMark 4 times.. and never used the Toy story lot..
Not sure if you have used the ART for the WorldMark before ... if you have then this info is for the other posters..
As long as you know the pick up times, and get out to the stop a little before you will have no trouble.. We never had any troubles with this route, and would be within a few minutes of posted times..
Sometimes in the mornings they would even put an extra bus on that route.... The WorldMark is the first pick up in the mornings and goes straight to
Disneyland.. on the way back it is the last, but with only two or three stops before hand , its not a long trip....
There is a an ART kiosk inside the WorldMark foyer... and you can buy a one way ticket on the bus.. although some of the drivers don't like that as it can waste time..
If you are taking a stroller then just make sure it is folded a little time before the bus gets there.. speeds you getting on...
and lastly.. there is no real line to stand at , so it can get a bit pushy at end of the day.. (everyone wants to go home) we would just make it real obvious that we were the start of the line, or if someone ahead of us.. we got behind them to get a line going... and most people were very polite ..
