If this is true then I completely agree. While a cluster addresses
both concerns of availability and performance, setting up for just
availability is easier. In addition if one focuses on just
availability one can perform certain tricks to allow for increased
timeliness with catastrophic recovery

The idea is that you want your www.site.com to be available from
either server A or server B?
If so, don't worry about switching your DNS. Instead,

a) mostly read-only - eg: two web servers that get the same content

I think the original question was around stateless load balancing, not

The question I have, are you trying to actually load balance things? Or just
have a remote location that you can fire up with live data at a moments
notice? Basically, are you wanting an active/active configuration, or
active/passive?
active/active across DC's can get kind of hairy depending on
feedback!
