CCI feels a little nicer, the grounds are nicer, the pool is nicer, the breakfast is much nicer. The rooms once inside seem equal or maybe not quite as nice as BWPPI. CCI has the shuttle which I use 90% of the time unless I just miss it by 2 minutes and have to walk. The shuttle pickup and dropoff is at the back of the bus area and only a 2 minute walk from BWPPI so if you ride the CCI shuttle you are about the same as the BWPPI as far as walking - but you have to be on a schedule.
BWPPI is closer and I like I can leave in the morning when I want and not have to worry about a shuttle. That is the big selling point for me. Location.
CCI usually runs a little more expensive by $10-20 a night. Not a big deal but it is there, especially when you have to get two rooms as I do when traveling with grown-up kids.
