Rates should now be inclusive in VAT our your reservation based on my recent emails with The Churchill.
If your rate changed from FLYER TALK GRP to HYATT DAILY RATE, forward a copy of your last correct confirmation email and include the correct rate information in your friendly request to correct the reservation. I started by sending the last (wrong) confirmation, which just showed the Hyatt daily rate and resulted in needing another round of emails.
Everything was very quickly and easily resolved with email. I love when I don't have to make a phone call. ^ The Churchill
