Slim. "Transportation options" is likely "we will give you $150 in uber credits. I am only going by my local service center, who had enterprise rent a car on site, and had at least 10-15 loaners available prior to Covid 19. They stopped providing loaners completely, and only provide uber credits now.
If you MUST have a loaner car, you will need to call them. Listen VERY closely to the prompts, and pick the prompt for "question about car in service now" or something. I cant remember the exact verbiage but the general verbiage is asking about a car in service. Thats the only one that I know of that actually gets to a person, in the service center of your appointment.
When someone answers, tell them your concern. You will likely find out that they are only offering uber credits, or, alternatively, they may have loaner cars (I just doubt it). You should be prepared for the possibility that you will have to use uber, so have a plan B in your mind.
The above is my opinion if you are getting any service that does not automatically look like a multiple day service issue. If you have a multiple day service issue, they "may" have a loaner car available but you should not go there with the *expectation’s * that you WILL get one, without confirming it with someone.
You can also text back to the text thread they should have sent you to confirm your appointment with your concern... that actually goes to the service center too and they see it on their computers I think.
