Hotel staff offer this rate to me

" We are delighted to inform that the extra bed can be set up in every room type with additional charge at XXX currency 1,531 net if room only basis, and at XXX currency 1,766 net for room inclusive of breakfas"

Hotel staff should to add informartion with the email that "the additional person charge have to base on original booking" but they didn't

Thus I think it's not fair for consumer.
