No detonator is a bit of a let down after angry birds land was advertised... Didn't expect loads of rides to be open, but X is a weird one considering it's indoors, a bit silly really. As what you've described isn't busy, maybe they have other rides on standby like detonator in case the park gets busier (well they'll know as it's prebook only). Should be visiting Wednesday and will be next Saturday, shall have to see.
