A new California law went into effect on July 1 which requires that mandatory fees (e.g. parking fee, resort fee, etc) have to be included on the booking page, but on the total cost page they can be separated by the nightly room rate and fees. Some things ( such as taxes, shipping costs if applicable) won't be included on the booking page, but will show up on the final page.
While room rates have been going up steadily, requiring that mandatory fees now be included in the nightly rate page has caused a lot of sticker shock.
