Las Vegas ?

[jcs11204]

I am planning a trip for early next year, i have never been there, and really dont know anything about the place, i have done my research on the internet but i want to hear from ppl who have been. I dont have any clue how much cash i should bring for a week, that is the main thing i am worried about, what to bring ? when i go on vacation or go to gamble i bring a set ammount, if i lose that, its over... no credit cards and stuff like that. What should i do there, where should i consider staying ? anything will help
thanks joe
