Hooray, I made it, although my ears have yet to get back to normal. Fingers crossed they return before Monday. Hungry now, so going to find food, I've had a tiny bag of free flight pretzels for the last 6 hours! Though it's gone midnight in the UK - on a Saturday night - so really I should be ordering a curry or a kebab ;)
If anyone is here and is thinking about visiting the Space Center, there's a wiki page and a suggestion of visiting the place on Sunday. Add yourself to the wiki and where you're staying so we can try and coordinate a meetup.
Powering up the laptop in the Hilton, I've found the free wireless :) The only downer is I really should have bought a new power adapter. Mine is definite 15+ years out of date. Mind you it still works ... just.
