I can finally post an official timeline!
We had a bit more complicated one since we changed home resorts. But start to finish 4 months doesn't seem too bad!
4/30-three night trip to HHI----came home wanting to add on
5/1-5/18-searching resales for a 'small' add-on, didn't find one that would work so we opted to sell our BWV contract to add more pts at HHI
5/31 ish- had a contract on our BWV pts, sent to ROFR
6/18 ish- found out the BWV contract passed ROFR
6/21 ish- put an offer on a HHI contract, sent to ROFR
7/5-found out we lost HHI contract to ROFR
7/8-put offer on another HHI contact
7/15-contract sent to Disney for ROFR
7/18 ish--closed on BWV contract
8/1 ish--received check for BWV sale
8/6--found out we PASSED ROFR on HHI contract
8/27-closed on HHI contract
9/14-MS found new contract in system
9/15-could make a reservation
9/18-had points and all loaded into our online account!!
So we sold one, bought another, increased our points and scored a June reservation at HHI all in about 4 months. And now we have Summers at the beach to look forward to the next 30 years....
