4 Sites each getting a new SonicWall TZ300, can all have access over site to site VPN's ?

I have a single company that has an admin and 3 branch offices.

We are outfitting each with a TZ300 and each is getting a static IP for the WAN and each site has a different LAN .
10.10.2.xxx
10.10.3.xxx
10.10.4.xxx
10.10.5.xxx
I have never setup more than one Site to Site VPN  for any business and am hoping that I can have 3 site to sites on each TZ 300
I know that I might be able to make some clever routing just at the Admin site but the client wants the redundancy.
I would like any comments before I start setting these up .....

Instead of creating a site to site vpn tunnel to each one, sonicwall full mesh vpn can fulfill your request.

The "mesh" is nothing else than either hub-and-spoke or spoke-to-spoke VPN. With the above information regarding redundancy, at least two VPNs need to be created on each site  (to build a ring), but I would set up a full mesh all VPNs on each site. A full mesh works best with static routes on each VPN device.
If the VPN device is  the default gateway, no additional routes (besides the VPN tunnel routes on the devices itself) need to be set up, clients are able to connect without.
