Hey all! Thanks so much for all the replies! Here's the exact way it went down.. I called the end of January to book the free dining offer, paid my $200 deposit. I asked the CM that if I had others (up to 3 others) that wanted to join on my trip, would I need to add them BEFORE the offer ended, or anytime, since I locked in the room. CM said I could add up to 3 more people anytime, even after the offer ended. Ok, great! My price alone was $1300-1400(w/o looking it up), with 5 day hopper. Then my sister jumped on board. I called to see how the $$$ would break down to let others know what it would be if they decided to go. Me alone was the 1300+. 2, 3, or 4 people, it would be $866 each. (that includes the extra adult fee) Ok! Next my step-mom jumped on board. Then my best friend. So, now we have 4 ladies going. I was talking to my sister and said.. ugh.. 6 nights all sharing 2 beds and 1 bathroom, were gonna be squished, I should have thought this out better. I went on WDW to check out special offers.. Room only, 20% off! Went to book it, no POP rooms left for that deal. Talked again with the ladies.. We all decided it was worth the extra money to spread out even w/o discount on 2nd room. So, my sister jumped online and booked that room. 2nd room, room only for 6 nights is just under $1000. So, we each pay the $866 + $250 for the trip, and we each get our own bed! AND 2 bathrooms!!! I called last week to add the 3 names to my original ressie (it still only had me listed) and they said my sister couldn't be listed in 2 rooms.. I just don't get why they care if we are ok paying $1000 more for extra space. Maybe we would all sleep in 1 room, and have the 2nd room for our dressing room! LOL! I mean.. the 4 of us are all getting free dining no matter what. Fair and square. They want to fill all the rooms.. I helped them fill another room! HAHA!
I'm going to take the advice and add sister to original room (FD room) with middle name. Thanks all for the help and advice!!! Can not wait until our trip!!!
