So let's work this backwards: What is your minimum requirements for breakfast?

1. Are you ok with cooking it yourself (or having a cold/microwaved/toaster breakfast)
2. Are you ok with a buffet, or do you want it cooked to order?

A hot, cooked to order, on-property breakfast appears to be incongruous with the price point your clients are willing to pay for your services. To wit, your options are most likely:

a. Learn to live with a cold/microwave/toaster breakfast, and stay at a property such as Homewood Suites where they'll go to the grocery for you and stock your full-size refrigerator
b. Stop and eat breakfast at a local diner
c. Find new clients.

My recommendation would be to do a week at a Homewood Suites and see what a true extended stay facility feels like.
