In a free for all match, can I voice chat with my opponents? 

One of my friends started playing Black Ops (it's her first FPS game ever) and to teach her how to play I created a private free for all match so we would be the only two players on the map.

I tried voice chat with her and everything was set up correctly (we could see the speaker icon above our heads blink when either of us spoke in the map).

Only thing is I could not hear her at all (the volume was up high).

I know in TDM you can't listen to the enemy chatter due to strategy and stuff but I would guess you could listen to enemies in free for all (for trash talking).

Anyway, to repeat, is it possible to listen to enemy voice chat in FFA?


Question: Can you book hotels on a prepaid credit card worldwide?
Answer: I did some research and could find information about the standards of Hilton Hotel Chain. They are one of the leading hotel chains and might set the standards for smaller hotel chains. 

Hilton offers also an American Express Prepaid credit card. See link: Hilton AMEX prepaid card. And you would expect that their own prepaid credit card would be acceptable for Hilton, but think again. 

In their FAQ they state: 


  Where can the Card be used? Are there any usage restrictions?
  THE CARD MAY ONLY BE USED AT THE FOLLOWING SELECT MERCHANTS AND RETAILERS AROUND THE WORLD THAT ACCEPT THE AMERICAN EXPRESS CARD ("SELECT MERCHANTS"):
  
  Hilton Worldwide portfolio of brands, which include Waldorf Astoria™ Hotels &amp; Resorts, Conrad® Hotels and Resorts, Hilton Hotels and Resorts, Doubletree by Hilton™, Embassy Suites by Hilton™, Hilton Garden Inn™, Hampton by Hilton™, Homewood Suites by Hilton™, Home2 Suites by Hilton™, and Hilton Grand Vacations™.
  
  RESTRICTION: Card may not be used to hold hotel reservations.
  
  We reserve the right at any time to add other merchants to the list of Select Merchants or to remove merchants that cease business, change locations or stop accepting the American Express Card from the list of Select Merchants.Please note that while the Card is usable at the Select Merchants listed above, it may not be usable internationally at non-affiliated third party establishments that are located within or on the same property as Select Merchants (e.g. coffee shops, boutiques).


I have checked many other hotel chains and I can`t find anything else about this. I do notice based on the information on the internet that if a hotel would accept it. They would hold at a minimum the total amount of your stay + 15% + additional amount for minibar and other used services as an guarantee. 

Some hotel would hold up to 3x the amount of your stay (I cant verify if that is really true). Just realize that a prepaid credit cards usually (not always) for people who have a bad credit record. Hotels take more protection when dealing with these kind of risks. 

Im not sure if the information will help, but at least you know Hilton Hotel is not an option.
