Well that depends on what you are looking to do here are some of my favourites
Miami - for hot weather hot women, good for single men on vacation not so good for couples, bars and clubs dont ever close open all night, lots of people beautiful beaches a non stop party if you go you MUST go to a club called BED its awesome, some tropical storms but not this time of year.
New York- you can visit lots of historical sites, shopping is amazing, times square is something to see for sure, beautiful buildings, romantic spots but rude people loud city and the most expensive city in america
Puerta rrico is still considered america but its like going on a vacation to the tropics, dancing romance drinking sexy fun, nice people and fairly cheap
Florida-orlando is great for families, aligator tours, disneyworld, tons to see and do that is all family friendly and there are also some adult things if you can find a sitter but its mainly a family destination
Las Vegas - if you want to live as a rock star for a week come here, fast fast fast thats all i can say, we have a saying here what happends in vegas stays in vegas because its sex drugs gambling music, many awesome shows to see, legal prostitutes, awesome strip clubs, great hotels and casinos, get back and tell me what you think or tell me any questions you have, if you like all the info that i have given you would you mind giving me a thumbs up and tagging mine the best answer because im trying hard to get into a new level. thanks so much ciao xox
