I have a feeling the increases will be around the 10% mark all over Villa Park - but it would be nice for the club to show some form of appreciation that there have been increases each season for a few years now and either pause for a season or increase with a small %.
I will be renewing my season ticket regardless of the increase (and I accept I am probably part of the problem for that), but I'm in a fortunate enough position to be able to afford it and wouldn't want to join the back of the waiting list queue when I change my mind. I can imagine for some the price increases each year are making renewal a real difficult decision, especially those with families and childrens requiring multiple season ticket renewals.
As for making the season ticket more attractive, they could pretty much do anything after last season to make improvements after stripping almost all of the benefits we were receiving. For a start just having some basic functions, bars, food and toilets available to use would be an improvement, although not exactly an attraction. The fan zones are great, but small and packed 90% of the time, I would personally move this to the Holte End car park, or have two either end of the ground with bars and food stalls. A discount in the club store used to be offered to ST holders, this would be nice to see back especially with the current costs of shirts and training wear.
I echo everyones thoughts on selling tickets, I can't understand why the ground has to sell out before they can be resold - and 100% of the 1/19 should go back to the ST holder where a profit is being made. The ability to transfer a ticket to a friend or family members fan ID should be available online - with possibly a limit on the amount of times to stop people taking advantage of a reference.
Give us all a free pint as well, because why not...
