Not sure what the rest of you think but if I'm doing 10-12 hour CCIE bootcamp days + labs when I get out and back to the hotel room, it doesn't make a lot of sense to combine that with an extra distraction (a pool, the Caribbean, etc) and pay $3K more for it.
Maybe it's useful if someone is looking for a free vacation for their work to pay for.
