Funding of Non-Relocating Parent's Visitation Costs: My 'ex' wants to relocate abroad. She says I can visit the children whenever I wish, but I can't afford it. If she wins the court case, could she be ordered to pay my flight and hotel costs?

This would very much depend on the particular circumstances of the case, but it could be possible, at least in relation to some of the visitation. For example, Tel Aviv Family Court allowed a mother to relocate with two minors to the U.K. in September 2005, and ordered her to foot the bill for a one week visit to London once a year. The flight ticket and accommodation in a three star hotel for a week were on her account, it held.
