Cramp is sometimes to do with electrolyte loss but it is also to do with muscle fatique and pushing beyond what you have managed previously (i dont just mean in terms of saddle time but effort levels) so even if you get the hydration spot on then you could still have issues with it on the big day particularly as with the adrenaline flowing and the big event atmosphere you are likely to push a bit harder than a solo training ride.
The ones you get in a tub which you add boiling water too aren't bad, not quite the real thing but a good compromise for a hotel room when you have a kettle and not much else.
Yeah experiment with everything you plan to use before the big day, dont do anything for the first time on the day. I am experimenting with quick n easy porridge as I will be in a hotel the morning of the ride so wont have access to pans and cookers!
