I want to take a trip to Bolivia with my wife and twin boys, age 3.  I
want to get a good deal on tickets and hotel, but I don't know what
site to go.  I looked up orbitz.com and expedia.com and hotwire.com
but I could not find satisfactory results.

I want to visit La Paz and Santa Cruz: about 1 week in each city.  I
am flexible about when we go: anytime Feb-May 2006.  I would like to
go for about 2 weeks, plus or minus a few days.  Any weekday for leave
and return is OK.  We live near LAX.  I want 4 or 5 star hotels in
each city.  When I tried looking this up at orbitz.com or expedia.com,
I got flights with 3 stops for around $900.  Three stops is too many. 
I want nonstop or one stop.  I know American Airlines flies LAX -
Miami - La Paz, but I could not get info about that on AA.com.  It
would be acceptable to fly LAX - Miami - La Paz, stay one week, then
fly to Santa Cruz, stay 1 week, then fly Santa Cruz - Miami - LAX.  I
know that AA does this.  I would like to flight tickets for this under
$800 per person.  Another airline is OK, too.  I also looked for
vacation packages (flight + hotel) but could not find any.  When I
type in some specific dates into expedia.com, it says there are no
packages for my dates.  But it will not tell me what dates are
available.

The AA flights you're looking come up when I search in Expedia, here
in the UK; details as follows (For departure 1 April; return 14
April):
