They removed the penalty paid for violations of the bed type guarantee (5000 points) on Jan 1, 2015

“One thing that will be changing effective January 1, 2015 is the existing bed type guarantee policy. Today, this is applicable to elite members only, and members are awarded 5,000 bonus points if the reserved bed type is not available upon check-in. Less than 0.1% of elite members did not receive their confirmed bed type – so in the future we’re guaranteeing that upon check-in all guests will receive the bed type confirmed, and there will no longer be any bonus points associated with non-compliance. Rest assured, the hotels are committed to getting this right!”

of course, a guarantee without penalty for violating it is worth nothing.

If I had needed two beds (e.g., because I was traveling with someone who I don’t want to share a bed with), I would insist on the bed type I requested with a room category I reserved or higher. If they can’t provide that, I would accept two rooms for the price of one.

If the don’t provide either, I’d request getting walked to another hotel. As a Globalist (OP, not me), I’d probably also call Hyatt Consumer Affairs if the Hotel was not cooperating.
