The super bowl host offers dedicated servers without much management. You either have to learn it yourself or hire someone from the outside or within that hosting company to do periodic management for you.
I have done the same move at the same host some years ago and haven't seen any rankings slide. Response time of the site improved (obviously) which increased user experience and eventually brought in more visitors. The SEO impact of moving servers is relatively low, especially if you stay within the same country or in your case even area. Local searches shouldn't be affected by it because your area doesn't change.
The only real thing you have to worry about is the propagation of DNS information which sometimes takes days before the rest of the world knows you moved. During this transition time you should keep up both the old and the new site and if possible with the same content. If the search engines cache the new IP address and find (almost) the same information at the new location, they will happily spider that new source. If the transition of IP addresses falls together with a site overhaul, the SEs algorithms might trigger a site owner change which may impact rankings.
