Cat almost all the buffets are gone. The few left gourmet and expensive.Don't gamble, it will cost you big If you want a 3 for 1 deal, hobby and SC in Canada. Don't go to SCs and hobby on LV, 3 to 5 times as expensive. Never talk to street hawkers, they do not have anything good to offer. Nothing is free. Only buy discount last minute tickets from authorized vendors. Check at your hotel consierge for the best places to buy tickets. Do not take any gifts or cards from people on the street. they will obligate you to pay. Never take a pic on the street with people in costume they will want $80-$100 from you. See the sights. If you do the buffets, do it for brunch or dinner and eat light the rest of the day. You can only handle 1 buffet every 3 days. You are close enough, so do San Francisco while you are there. The 2 weeks just before and after Christmas you will find about 60% of the crowds have stayed home.
And as for San Fran its a shithole now. Especially driving into. Until they get a handle on their homeless catastrophe don't go there.
The rest is standard tourist shit in the USA. I can the same about NY and other hubs.
