Always call to check reservations when possible. If there are issues, you want a change or have questions there are people paid to make sure you are taken care of. That is my recommendation. Plus, that is the only way to get hook-ups and deals after the fact. Only the initial deal is usually better online during purchase, there are exceptions of course.
Depends on how you made yoiur reservations in the 1st place. If you made them online, you can check them online. Or if you called them in you can simply call them. Hope this helps.
