I recently had a chance to visit Adventure island in Delhi and as compared to the other amusement parks I have been this one was pretty mediocre as 40% of the rides were non functional, not to forget the worst cafeterias and no place to stand under the scorching heat of sun , yes the market on the entry was quite good with all major brands but once inside the park nothing was memorable the adult rides are scarce and most of the rides are for under 16 age group.
But yes parking space is pretty good and roads are excellent.I would advise a visit in evenings and in spring and winters never in summer afternoon.
