I was first leaning towards buying/renovating/running a bed and breakfast at the beach, but I also love the idea of buying an old motel and turning it into a sort of boutique/upscale motel.I guess my question is, what should my plan look like to accomplish this?

Same location and you can still have breakfast together, you just sleep a little farther away!  

It is not great as a place to learn from successful RE investors.Wednesday: Meetup: Apartment Investor Mastery (Multifamily networking and education), Meetup: Passive cash flow (How to invest in 2020)Thursday: Meetup: Commercial REI Breakfast (Using virtual assistants to build a stream of off-market deals). 

I also like the individual room AirBnB vs entire unit..as @Ryan Aydelott said entire room AirBnB will attract larger group of people normally looking to throw parties...safer to list individual rooms with amenities such as wifi, neat and clean bedroom/bathroom, breakfast areas, work desk etc which will attract business travelers and younger population.

I know it came with frig, stove, 2 single beds, couch, chair, end table, coffee table, 2 night stands, 2 chairs at a breakfast bar, and cadenza for a tv stand.  

Another option may be keep the bottom wall up and have like a breakfast bar so it still feels open.

I learned by going to meet with a bunch of wrinkled old landlords who used to meet for breakfast every Friday at a restaurant in Orange County.

Bed and Breakfast - a real one, not AirB&BConvert to assisted living (@Bryan Otteson might have an opinion on this)

If you are or ever could be that way during the week for breakfast or lunch I would be glad to connect! 

In the ad, they state you receive a free breakfast (How is the breakfast?)
