If you need a 2BR, the probability of success is much greater - there are only a very limited number of 1BR and Studio accomodations at HH. Not sure why, except Member documents suggest that DVC research showed a strong demand for "dedicated" 2BR units (the vast majority of units at HH are indeed 2BR "dedicated" units). Based on my brief experience in DVC, you should have no problem getting a 2BR reservation within the 7 month window for most seasons. Studios and 1BR's are MUCH more difficult.
