Chichen Itza bus question

[pkix]

We're considering doing Celebrity/RCCL's ship excursion from Cozumel to Chichen Itza in late March. We've read loads of reviews both here and elsewhere, and so have some idea of what we're getting into (long, bumpy ferry ride, longer bus ride, maybe 1 hr at the site if we're lucky), but had a couple questions about the bus itself. Is it a regular long haul-type tour bus, with AC and a toilet?

 

We're aware there's an air option for flying to Chichen Itza, but won't be doing that. Thanks in advance to anyone who can answer my question!

I took the bus many years ago , I think it took about 2 hrs to get there and it was very hot at the ruins ,I am glad I went.............https://youtu.be/zPlbGtVxaFc
