Interesting fact: the original Regis hotel in Mexico City was on Juarez Ave, built in 1910. It collapsed in the 1985 earthquake and killed almost everyone who was inside at the time.
So, there's not evening Club/Lounge available? And whatever the Butler brings you there's a charge for that? I'm not sure why people pay so much for this hotel when you can stay at the Hyatt with a Club Lounge.
There is no charge for the butler service. But if you order food, then you will have to pay for the food. There is no Club or Lounge available, like at other Marriott properties (Executive Club or M Club, for example).
