Your chances are good and you've already identified the main potential weakness on your app which is vet experience hours.
55% of cornell's application is weighted on your academics. Only 20% is weighted on experience (including vet, animal, and research/other biomedical).
As long as you meet the minimum requirements, go ahead an apply this year. If being IS at Cornell would make a big difference cost wise (or quality of life wise for proximity to family) maybe only apply to Cornell and then expand your list of schools next year if you don't get in.
Keep working on vet hours in the meantime - if you need to apply again in a year, you can rack up hundreds or even thousands of hours during that year.
Lean in hard to your experience as a simulated patient and hotel employee on at least one of your essays. Having good client skills is a huge part of vet med - you can talk about people skills you gained at the hotel and can talk about what it was like to be a "patient" - I'm sure you have a lot of insight into what makes an appointment go well vs poorly! It's also a cool, unique experience that can help you stand out.
Schools that weigh academics heavily and don't interview have a bit of a reputation for producing vets who are... not as well rounded at client skills.
Meanwhile, the AVMA just posted an info graphic today that showed that the #1 reason for satisfied clients and client loyalty was how happy they were with the friendliness of their veterinarian. Those clients are also more likely to recommend other people to the practice. Expertise is definitely up there too for clients, but client communication skills are super important.
I think your academics are competitive, and if you are smart about your recommendations and essays I think you can set yourself up really well.
