Should be forever. Two of the "three lines" you saw were Fastpass line entrances. It is set up like the new TSMM FP entrance or FoP with four touchpoint instead of two. All new rides with a decent capacity are being built with four touchpoint to alleviate the congestion and backups that two caused.Is that just at opening or forever? I ask because the entrance seemed to have three line options, just like MFSR.
