Hi There,
I am going down to WDW and will be staying at BLT in January.

(very excited as it will be my first time at BLT.) I am a member of DVC, but my guests, DSis and DN are not. If I have my card can we go up to the TOtWL?
As long as they park in Macon GA or Jacksonville - yes.
Just kidding! Check out other posts.
From my experience - We went over there with 8 of us from our OKW GV and 4 others who were CM's - seemed like e1 coming from a different spot. You speak with the Host/Hostess and a Concierge gets you on the Elevator. As new folks showed up I went down and escorted them up.
I think one day we parked at the MK Lot and left MK an hour before the show - a good way to do it.
One person needs to show their Room Key / Id / or whatever. Then they escort you to the Elevator. On one night - a few members in the group went over and got food from the CR Kiosk - they asked the gentleman to remember them - as they would be coming back. I told them - call or text if an issue. No issue.
I may be wrong - but - one of the kid's friends who worked at the Wave (in CR) came over after work. I explained to the Gentleman in charge that X-person was coming over - I am willing to come down and show my ID - or - can I give you his name so you can let him up? He was great to deal with and said - give me his name - no reason for you to come down. We texted this guy the info - no issues.
Every night we were there a CM came out and counted the folks in attendance. Three consecutive nights in July 2013 - the max was about 120. The CM told me he was happy that more and more folks were attending - but admitted he hoped the word would get out to more folks. 120 folks over 2 hours does not even come close to the bar at the pool at Poly - where this guy used to work.
I was just interested he was doing it and asked him each night what the count was. I can be a chatty one - and talked to lots of folks, Most folks were not staying at the resort - most were from other DVC resorts.
On one (maybe two?) nights - before the show a waiter came out to get drink orders. Very cool.
Was never crowded outside- this is a HUGE pavilion up there. Did get busy after the show in the Bar - but we always found seats.
Great Perk - it is so cool to just look over the Park, Lake and other resorts. Would recommend to any and all!
I am really awaiting the next: "The rules state...... Bom - follow the D@mn rules" Post. Save it Please! Maybe I broke 14 other rules - but - may be ignorant of the rules - but was polite and explained my intent. Had anyone from the Guards or the BLT staff had a concern - I would have listened and not complained. I am a good customer and spent Green Money there.
One persons experience. That I cannot park there - a different story I will just deal with! But, I hope e1's experience is as hassle free and delightful as ours.
