After working for a small ski resort for 3 years with no room for advancement I decided it was time to move on. I searched for a couple of months for something that I would enjoy as much and ultimately couldn't find something for another resort. Instead, I accepted a job for a hotel company (job A). The hotel group is great and theres a ton of potential to make this role really awesome. Unfortunately the salary came in 6k under what I was hoping for but after a lot of negotiations back and forth they agreed to a 6 month review to bump my salary up a little bit They also don't offer health insurance so while they agreed to pay a small insurance stipend, I am still taking a hit to my bottom line pay. 

The day before I started job A I was approached by a ski resort with a job opening that was slightly better than my previous resort job. I decided to interview just in case and found out the job B could pay a good amount more than job A, possibly up to 15K more and they offer health insurance. It seems pretty promising that I will get an offer and I really thought I wanted to stay in the ski industry.

Now I am torn on what to do - I really like job A despite it not being a ski resort. The people seem awesome and I get a good vibe already. I will have a lot of freedom in this role plus there is a lot of potential with this company to grow and likely a good future for advancing my career. On the other hand, Job B would pay more immediately, and would keep me in the ski industry but there's nowhere to move up in the company so I would likely be capped on what I could do. 

If I get this offer should I say anything to job A? Is it too late to negotiate my salary more and stay? If I do decide to leave for job B, what should I tell job A? I don't want to be unprofessional but it would be hard to turn down 15k more a year...
