I'm sorry to bring bad news but it is highly unlikely that you will get into HH this summer for several reasons:
1. The majority of the rooms at the resort are dedicated 2 BRs. Here's the link to a thread with the resort layout and other information.

2. The summer is the most popular time to go to HH and it is a small resort.
3. The DVC members that wanted to go to HH and own at other resorts were able to go on the wait-list this past winter (7 months out) and they are all ahead of you if a room were to become available.
I'd say that it is highly unlikely that your waitlist will come through but you can always try.
Easter will be difficult too. Hoping to get in during the busy summer season or during a holiday as a non-owner can leave you dissapointed.
I hope that this information was helpful even if it probably wasn't what you wanted to hear.
Good luck.
