BZE to San Ignacio Feb 3

We are looking for people to split a shuttle from BZE to San Ignacio. We could cut cost down to US$25 pp if we can get four additional people, there are two of us. I've made contact with a shuttle operator that is recommended by others who’ve used him, he said it takes 2 hours to get there and he’ll make it worthwhile.
I looked at other options and all require getting cab to the bus terminal at some crazy cab fare. I guess gas is US$5.80 there, so expect to pay high $$ for cabs. All in all, I think splitting a van is the best way, it’s a time saver, and with the right amount of people, it’s worth the cost.
We land at BZE at 12:30 pm on Feb 3.
While I’m checking around, I might as well ask if anyone is heading to Tikal the next morning. Split a cab at the boarder?
Happy travels.
