Can you please help me get to my dad?

Can you please help me get to my dad before his health gets worse?

My dad lives in Arizona and comes to see us in Idaho during the summer to celebrate our birthdays (mine, my mom's, his, my husband's, and daughters'). He was preparing to head this way within a couple of days. However, on the morning of June 10th, I woke up to a text from my sister telling me that my dad was in the hospital. His neighbors thought he may have had a stroke, but he had texted her that he was okay. After waiting all day for someone to tell us what was going on, we finally learned that he had indeed suffered a stroke. He was lucky and thankfully still had his sight, hearing, speech, and memory but had very little strength in his left arm and leg. He was sent to a rehab facility where it was discovered that he had fluid around his knees from falling when the stroke occurred. He was then transferred to a different rehab facility and last night had to be transported to Las Vegas for an MRI due to worrisome increased tingling. We are currently waiting to hear any updates on his status.

Update: He has had another stroke. Thankfully he was lucky again and retained his basic functions and memory, I fear he won't be so lucky if he has another. He is turning 80 this year, so I'm still very concerned about his health and susceptibility to future health issues. He has been transferred to a rehab facility in Las Vegas for two weeks, at which time they will check his progress and decide the next steps. If he ends up being released from the hospital he will need to figure out how to get back home or to a different rehab closer to his home. I would like to be there so he doesn't end up stuck in Las Vegas.

I need to get to my dad before it's too late, but I have limited funds for gas and lodging for a 4 day visit. Any help would be greatly appreciated.
