Just a warning about SBP -- only the red (summer) one-BR weeks will pull a 2-BR Harborside, and it's very tough to get Starwood to deposit one for you (you have to be the squeakly wheel). I didn't have a chance last night to play around more, but my past experience has been:
2-BR Summer BP will pull any Harborside
1-BR Summer BP (small side and large side) will pull any Harborside, including a 2-BR .... and WSJ
2-BR Pink BP (May, Sept) will pull all one-BR Harborsides, and some (shoulder season) 2-BRs
1=BR Pink BP will pull all one-BR Harborsides
Red seems to be approximately Memorial Day through Labor day. Pink seems to be May and September. The platinum season in the older phase of BP runs weeks 9-43 and 47. If Starwood sticks you with a lousy week (March, April, October, November) -- you probably won't be able to pull the Harborsides unless they're in flexchange.
This is not scientific -- just from memory of doing past "trade tests" with my various weeks when sightings appear. (Note, have never done a "trade test" when WSJ appears -- that's a GRAB AND RUN situation!!) Just thought a general caution might be helpful ... I wouldn't want anyone to buy BP without understanding the full situation.
All this is pretty true of PGA as well -- but the seasons are different (Feb, March and April are red). They (PGA and BP) are probably the best bargains in the system from a purchase price, maintenance fee and II trading perspective. But, they're not riskless due to the deposit policies (which I'm going to continue to challenge until I see legal proof that they have the right to control the deposits for non-SVN members).
