I think that sequence (Circle, swing, circle, swing) is usually not to 
bad for beginners. You just need to be sure they know where to swing. A 
nice thing about this sequence is that it is very well connected. That 
is everyone always has the hand of someone else who can lead them to the 
right place. Its much more difficult to get lost if you always have a 
hand to guide you and to reinforce your (hopefully correct) motions. 
That sequence is also used in the dance "Roll in the Hey" (Who wrote 
it?), which starts out:
A1: C L 1X; Swing neighbor.
A2: C L 3/4; swing partner.
Then:
B1: F & Back; Ladies' chain.
B2: Hey for 4.
Except for the hey, you are always connected to someone else who can 
push or pull a beginner in the right direction, if necessary. I like to 
use this dance when I need to introduce the hey, because the hey is the 
only complicated part that needs much instruction, after beginners have 
gotten a few of the basics down. It works very nicely with smoothly 
flowing tunes, too. Its also a good dance to mention the need to glide 
smoothly, rather than bouncing like a beginner, if necessary.

Jerome Grisanti remarked on 12/8/2006 1:00 PM:
  One of the questions Rickey asked was whether dancers
would have trouble
 with the sequence of circle, swing, circle a different amount, swing. I
 don't think this is particularly confusing sequence, but there may be other
 issues worth considering.
 Cary Ravitz (
http://ravitz.cnc.net/dance/call.shtml) suggests that dances
 with more than 32 counts of consecutive clockwise rotation should be
 examined closely. This dance has exactly but not more than 32 counts of
 same-direction movement.
 I would avoid doing more than one or two such dances in an evening's program
 because of potential dizziness and the wear on one's legs and arms of so
 much motion in the same direction. Given that, I can see this particular
 dance as a good "cruiser" requiring only a minimal (or no) walkthrough.
