Sinkieland should do away with the SAF live firing area and build a third bridge to Greater JB, reaching directly to the Puteri Harbour area.
It's already a pain to travel from the Causeway or the Tuas Second Link to Legoland, and there's a long distance from Legoland to Puteri Harbour (where Hello Kitty Land is).
