havent been to I drive for a few years,but the I drive buses you are talking about dont go to disney,there is a lyxn bus number 50 you can get near sea world but its alot of hassle to do,better off using transport to parks if your hotel does it,might be best to check hotel if they do transfers to disney.
plenty of places to eat we always used the ponderosa for breakfast there are 2 on i drive depends where you staying,you might be best to look at google maps to see where your hotel is and look for places close...theres a link below for the i ride trolley site,,tells you on there places to go and eat and prices..
