That is a very unfortunate start to your trip. The dirty bathroom is gross, but I would have been content with someone coming up to thoroughly clean it asap. However, the condom in the bed would have truly stretched my ability to calmly address the situation, so I very much understand your dissatisfaction. Thankfully, your requests were granted and you now have a resort upgrade (hopefully at the same price you were already paying), so that's a big plus. However, I would still email guest relations and give them a complete, accurate rundown of what happened, including what POP's manager did to remedy the situation. Sometimes it helps just to feel like your voice is being heard, and guest relations will definitely get back in touch with you to acknowledge the issue. Also, it's a good idea to let someone outside of POP know about this so the matter can be universally addressed with all of its managers and housekeeping staff. Guest relations would be the appropriate place for doing exactly this since the messages are distributed to the teams responsible for whatever the complaint/praise is about. If it were me, I would be content with phrasing my message as "I have already received compensation for my troubles and in no way am asking for anything more, but this situation was disturbing enough to warrant documentation with your department (guest relations) . . . " I would send it off not expecting any other compensation but at least knowing my voice was heard and the matter would be looked into and hopefully steps would be taken to prevent this from happening to someone else.
I hope you enjoy your new resort and the rest of your trip is trouble free.
P.S. Here's the email address for guest relations:
WDW.Guest.Communications@disneyworld.com . We use that address often during our trips since we make it a quest to collect names of cast members doing great jobs. I want them to know their efforts were noticed and appreciated.
