Final answer:
A reservationist should first offer a caller a room that best meets their needs and maximizes revenue, generally a mid-range option that balances quality and budget.
Step-by-step explanation:
All else being equal, the reservationist should be trained to first offer the caller a room that aligns best with the caller's needs and preferences, while also maximizing revenue for the establishment. Typically, this strategy involves presenting a room that balances both the guest's budget and the more premium options, often referred to as "mid-range" offerings. This sales technique not only promotes customer satisfaction by tailoring the service to their needs but also encourages a higher spend without immediately suggesting the most expensive option, which might discourage the caller.
