Not much activity on this thread for 2 years, need some advice. Travelling with spouse and a 2yr old, I know that Europe can be sticky with a 3rd guest, all prices seems to shoot up when I add in my 2 yr old.

Option 1- Currently booked for 2 at the AC Recoletos for 2k (I called and emailed and they were able to add my son to the reservation at no cost) - Not a fan of AC hotels but seems to be the best value for money considering location.
Option 2 - Retiro is about 3.2k for 2 guests, have emailed to enquire about additional child
Option 3 - Westin is almost 4k for 2 guests, can't seem to find their email

All 3 have outrageous points cost 420k - 490k for my stay (8 nights)

Looking for suggestions/thoughts? Also since I am platinum will the included breakfast include my 2year old or will that be an upcharge as well?

Circulo will not allow kids so not an option.
