Absolutely! The staff members at Disney's HHI resort have the reputation for being the friendliest CMs anywhere, and it's deserved. They are incredibly friendly, helpful, and informative. When you show up to the resort, there's a small gate w/arm you have to get through. Just hit the button on the intercom to talk to a CM in the registration office, tell them you're members wishing to check out the resort, and they'll buzz you right in. The main building is straight ahead on your right, and there are plenty of visitor spots to use. Go up the steps in to the office (take a quick peek at Shadow's doghouse) and step over to the desk to speak with a CM. From there, go exploring at your heart's desire. We've done this a couple of times (I've also stayed there years ago) and grabbed Mickey waffles as it was morning. We walked around the grounds, bought a couple of items from the gift shop, and just soaked up the atmosphere. If you want to check out the beach house portion, you'll have to ask the CM about that. We drove over ourselves with our
DVC member cards in hand and got in, but I wouldn't necessarily think that's a great method.

Have fun!
Oh, as for the seven months out possibility, the odds are very low if you go during any of the typical peak times such as spring break, holidays, and most especially late spring through summer. Very tough to get in.
