very disappointing that so little of the site is currently open.They only seem to be working on one building at present yet have ripped out the walkways and closed most of the site much earlier than necessary.With a little planning they could easily work in stages and keep most of the site open.What you can see is fantastic but its very frustrating to see tantalizing distant glimpses of so much more in the closed areas.I will return one day when its fully open but unless they get their act together I suspect this may be years away.
