OK, so you mean a virtual hop, not a virtual host.
You do not need a virtual hop to fail over among several WANs. The purpose of using a virtual hop is to allow monitoring of availability of a given link using several hosts in the internet, so if at least one of those hosts responds to pings, the link is considered working. Without it, a fault of the single monitored host causes the link to be considered unavailable.
So this has nothing to do with the number of WAN links and with the way you use them (exclusively by priority or distributing the load among them or a mixture of these).
thanks for sharing, if i am using 4 WAN load balance from:
