No never go that time , too much crowded as the tickets are very less. If you want to really enjoy the rides then due to over rush you cant . Better go any other week day with some discount from other websites and easy enjoyable.
Nope, don't go on Tuesday or weekend also, it'll be more crowded and you have to be in long queue for every ride which is frustrating. So better go on any other weekday.
There are websites like beyondenough, grabon which gives discount coupons with packages including food and pictures do check that before going!!
If you take pictures packages do get clicked by their photographers before 6 as after that photographers will not be available.
Hope this helps
