i've only recently started becoming more interested in finding ways to accumulate as many points or miles as possible and have a question regarding third-party booking sites such as expedia or travelocity, etc. is it true that if you book flights or hotels on their websites that you won't get the full point credited to your respective hotel or frequent flyer account? i stayed at a hilton in san francisco after having made the booking through expedia and when providing my number at reception they told me i wouldn't get points credit for the stay, only the additional expenses i would pay such as food and beverage, etc. which is pretty disappointing if this is true or just incorrect information on the part of the receptionist, because then what is the point of using these sites to book other than ease of browsing?

any thoughts would be welcome in helping me clarify this.
