I really hope it isn't cancelled for those booking online - whilst I understand annual pass holders want it as an exclusive, as previously mentioned, I doubt the impact it has on queue times is substantial.
It's also perfect for people like myself who often travel to Alton for the day once or twice a year who want to get the most out of park opening hours - my visits aren't frequent enough to warrant purchasing an annual pass nor can I afford the hotels, so buying online and getting the extra hour on park is great. Just to echo previous responses, getting rid of this for online bookers seems to be less efficient and would risk getting rid of it altogether - it'd be interesting to see the percentages of people taking advantage of early ride time (booking online, staying in hotels or AP holders).
