AD DS Site and Subnet Design Decisions

hi all, 

quick q, deploying new ad ds deployment on 2012 across 5 uk sites.  i following following ms article sites , dc deployments  as defined here http://technet.microsoft.com/en-us/library/cc731569(v=ws.10).aspx.  one decision document defines is, if site has more 100 users dc should deployed locally. each of our sites have >100 users.  

i know ms best practice should followed sites have resilient bw in sites these sites, experience should these sites consolidated in single site?  we removing exchange services no local ad ds reliant servers present?

my thinking consolidate sites , dcs if goes wrong such latency issues guess first question asked did follow ms guidelines!!

on 2nd note have dr site no users present, looking deploy 2 dcs here.  could site consolidated in site here 1gbps link other site resiliency?  agian thoughts here work fine means users in local site authenticate locally , dcs in dr site

thanks

as long bandwidth , latency acceptable user experience/application performance standpoint, there nothing preventing consolidating multiple physical locations single site. unfortunately user experience subjective - that's not can determined based on particular guidelines. need test it.

the same applies dr site - although in case, might want use dns srv records priority settings ensure 2 dcs not used long production dcs available
