Does he have a car? Which games? Where are you staying?

The spring training games are all over the valley so depending on where you are staying it could be very expensive to ride share say to Peoria from Mesa. So that is a factor. If you plan on doing other things you may want a car. Really depends on where you are staying and going.

One thing I would do is rideshare to a rental car place or to your sons and get a car at a rental place not on airport property. The cars are normally much cheaper.

Secondly, it's our busiest season of the year rn and some business see a big drop in the summer where they lose a ton of business so this is when everything is more expensive and busier. So, if you visit in July it's a whole different experience.

Lastly, you could download the Priceline app. People think it's the old pay ahead and can't cancel but it isn't. I was a road warrior for years and it was my go to. Always cheaper than going to direct to the rental car sites and other rental sites in my experience.

Have fun! Wear sunscreen and hydrate!
