I've never seen a crit heavy "stage race". Plenty of omniums of course. Really no purpose in such an animal I suppose.
The OP would be wise to also look into races throughout Latin America. Plenty of multi-day stage races with zero crits involved. Just gather up 6 guys and a support person, email the promoter and maybe you can secure a place. Your only cost will be plane tix. Most of those races cover lodging and offer up some food usually as well. And will get you a truck for the caravan to boot, sometimes with driver.
