We might be changing to the Cosmo for a 3 night stay instead of the Mirage. I'm paying cash for the resort fees and taxes and planned on using a low limit credit card ($300 only) for the incidentals since Mirage is only $50-$100 per night hold. We have closed all but a few credit cards (fixing our debt) and this is now our only major one with a zero balance. Anyway, I read that the hold at the Cosmo is $150 per night, which our card won't hold. Has anyone had any luck with the front desk being able to adjust that upon check in or is it strict un-bending policy? I'd like to stay there and not let this be the reason why we can't. I just need them to auth $300 instead of $450. We have a resort credit to use so we have to be able to charge back to the room so they can apply that. It's only $100 so it wouldn't go over the amount held. Thanks in advance.
