you figure around $400 per night if its busy season for hotel/condo.... $300 day for food/drinks (family of 4), $200 tops for "souvenir" type stuff before you leave and $4-500 on entertainment (shopping, theme parks, rides, etc). For 6 nights that would put you around $5,200-$5,500 for a nice week assuming your travel days you're not eating like a king.
