Personally, I'm against having BXP weekends, because these events benefit mainly those who accumulate huge quantities of goods to earn profits, and cause prices to increase so that you end up barely making any savings from the bonus XP.
These occasions also encourage sharing accounts and unhealthy gameplay, as the XP multiplier doesn't decrease to 1x after 10 hours. Summoning also receives an additional bonus to actual XP gains regardless of Summoning spending the majority of its time collecting charms. The bonus is only 1.1x after 10 hours, but it doesn't make any difference.
Additionally, I am not a fan of how these events are created with the intent to increase revenues on days when the majority of people would have to cancel their the school membership. However, I don't know what you'll do with the extra XP. I'm likely to end up runningecrafting to fulfill the requirements of the Karamja diary.
