I would think that moving and not incurring additional costs from going from a Value to a Moderate would depend on the reasons that you are not happy with your resort. Last summer my kids and I were at CSR for a planned 10 day stay. 3 days in, and we knew that it was not going to work. We had major issues with housekeeping, noise all night, bad language, smoking, drinking outside of the rooms from a group of conventioneers etc...that we were placed in the middle of. It was really bad, and I am not a complainer. I went down to the front desk and politely asked if we could change resorts, and why. (In this case, from Mod to Mod (POFQ). The cast members were great, and within an hour we were packed up, taken by taxi to FQ, and given an upgrade to a river view room at no cost to us. If we just didn't like the resort, I am not sure we would have been able to change without paying the upgraded cost. I do believe that Disney wants their guest to be happy, so I would do as the others suggested and speak to the front desk, sooner rather than later. I wish we wouldn't have waited 3 days. Good luck.
