It's currently 23 degrees with a wind chill of -20 at my house, so I'm focusing on our trip to DW in May today and I have a few questions. I've tried searching for these answers and either couldn't find an answer or found answers from several years ago that might not be accurate. A little background. This will be my 14th trip to Disney, but our first stay at a Deluxe resort. We're in a Resort Studio in Big Pine Key (paying cash, we're not DVC). For our last 10 trips, we've had between 2 and 5 of our children traveling with us, so we've always gotten 2 rooms at Pop Century or a suite at AoA. This is our first trip with no kids (though our "kids" are all over the age of 21 now). So while we're very familiar with how things run and where things are at those resorts, we're clueless for this resort (though we've eaten here and explored the resort several times on the last 2 trips). So, here are some of my questions that I could use help with:
1. At the Value Resorts, we've always borrowed a luggage cart from bell services to unload our car and take everything to our room ourselves -- not because we're cheap, just because we like to be in control of our stuff.

Can we do this at the GF or do we have to let bell services do it?
2. Which self-service parking lot do we use? The one in front of the main building or the one in front of the DVC building? Or will the parking lot gate attendant send us to the specific lot we need to be in?
3. I typically do online check-in, but if we need to go to the front desk for something, do we go to the main lobby or go to the DVC building (again, we're paying cash. We're not DVC.)?
4. I'm assuming that if our room isn't ready when we arrive, we can leave temperature-sensitive food items with bell services and they'll hold them for us. Is that true? And once again, bell services at the main building or at the DVC building?
5. Any recommendations for room location requests? We booked a preferred view room at BPK and would like to be in a sort of quiet area of the building -- away from high traffic/noisy areas. I know the "quietness" thing really depends on the people in the rooms around you and that room requests are just that, requests, but if there are rooms that always have noise (from the lobby, from the housekeeping carts congregation area, etc.) I'd like to try and avoid those. I know AoA like the back of my hand. I know what areas we like to be in, so I know what rooms to request. This resort is a whole new ballgame for us.
Looking over these questions, I guess I really just need to know if we use the DVC amenities/services because we're staying in a DVC building, or do we need to use the main building services because we're not DVC members? Or can we use either?
Thanks for any help you can offer!
