Few people have posted in the past that they would like to come from Auckland to home games and not stay the night and pay out for hotels etc, but the 7.30pm kickoffs mean you can't make it to the airport in time for the last flight of the night. Noticed Mana Bus have launched a new sleeper bus service between Wellington and Auckland this week, leaving daily from Bunny Street at 11pm, scheduled to arrive in Auckland at 8.45am and includes lie-flat beds. For example, for the home game on 14th Jan there are currently sleeper bus tickets available for $25.99. Would also give you time for a post-match drink or two before it leaves. Don't know how comfortable or easy it would be for sleeping, but could be an option to think about for those who have been put off by not being able to make the last flight back.

Edit: Could also be an option for Wellington based fans travelling to Auckland games and not wanting to stay the night.
