Allsorts,
As you look out into the dolphin area there are a couple of sandy "fingers" that reach out into the dolphin area. Pick the one nearest your group , get hold of one of the small chairs ( with small legs , I mean ) and plonk it into the sand...AND SIT THERE!!!!!!!!!!! Make sure there ain't room for some large American to stand between you and your view of your family .....because they will , given half a chance! As I recall there are some tall palm trees , lean your chair aginst one, A) It gives you support and B) it stops anyone walking in front of you!
Do NOT try to stand and video for the full half hour, unless you're named Superman your arms will feel the strain after 5-10 minutes and your video will look like you took it standing on the wing of a moving aircraft!!!!!!!!!!!
You'll love DC, ..............AAaahhh memories!
