You already host your website somewhere or else no one could see it. When hosting, you have an option to upgrade to SSL which website visitors insist on now. It seems that everyone, everywhere, highly recommends that you make this change to secured hosting.
We have partnered with an SEO company with a long history of promoting Bed & Breakfasts. I believe they will serve your business well and recommend them highly to help your business Seo. They provide the Hosting offer mentioned above. I have always had issue free service from them.
Considering the old rates for Insecure HTTP hosting, caution is understandable if you are deciding to upgrade your service. It will cost twice as much and you may not even notice a change. 
While I can almost agree that the expense is unnecessary, here is the bottom line for any B&B getting business online: That pesky notice of security in the address bar!
Very possibly most web surfers refuse to even visit websites that are labeled a security risk these days. And for reason too.
In September, 2018 Google again (their constant message for many years now) had this to say about SSL Certification:
"HTTPS helps prevent intruders from tampering with the communications between your websites and your users’ browsers. Intruders include intentionally malicious attackers, and legitimate but intrusive companies, such as ISPs or hotels that inject ads into pages.
Intruders exploit unprotected communications to trick your users into giving up sensitive information or installing malware, or to insert their own advertisements into your resources. For example, some third parties inject advertisements into websites that potentially break user experiences and create security vulnerabilities.
Intruders exploit every unprotected resource that travels between your websites and your users. Images, cookies, scripts, HTML … they’re all exploitable. Intrusions can occur at any point in the network, including a user’s machine, a Wi-Fi hot-spot, or a compromised ISP, just to name a few." - Google Developers
If your website is NOT secure then you expose your viewers to intruders. Seems slightly abusive, and as more and more people understand this, un-secured websites will receive a continually dwindling supply of visitors.
Is that disturbing? It should be. Take your own informal survey of customers visiting (or rather who used to visit) your website. Does the insecure notice in the address bar deter them from visiting your website? Does the notice deter you from visiting someone else's websites online?
BnBSeo offers us both, hosting with the SSL Certificate, for $170/year. "We require a one time setup fee of $65. We cover any problems encountered during setup or changes your wish to make later. We also provide regular monitoring to assess validity."
Your business appears online in many places tagged with various keywords. Most of those words, which greatly effect how your website ranks, are under your control as they are on your website. If the words on your website are the "best" ones for your business, AND they are used "properly" across your website, others are likely to use those words also when linking to your website. Those words are the ones which you will rank for and must accurately describe your Inn better than your competition.
Let them straighten it out and insure that your message and details are strong and true, bringing the customers who want YOU.
