We just returned a couple weeks ago from our first Disney World trip together. And I'm happy to report we didn't have any negative experiences only 'magical' ones!
At check-in the CM didn't miss a beat when I told him it was my wife's B-day and our 1st trip together. He gave her a 'It's my Birthday' button, me a 'I'm celebrating' button us both 1st visit buttons. He noticed we paid with a Pen State Alum card and they struck up a conversation about Pen state. (He was there on a college program with Disney.)
We did a couple tours and both or our CM's were great & welcoming. The other guests were also friendly & welcoming. We walked arm-in-arm or held hands often during the tours. So, it was pretty clear between that & the introductions we were a couple.
(If anyone had a issue they kept it to them selves.)
Any cast member's we actually talked with caught on pretty fast again never missing a beat. They were all so cheerful and welcoming.
At the AK we were walking along one of the paths near water fall and spotted a Photopass CM. It was not too busy of a spot so we jumped at the chance to get some good pics with out strangers in the background. So, we asked him for some photos, he took a few shots then asked if we were sisters. We said 'nope we are married'. He paused of a second and asked 'you two are married to each other?' We both replied 'yes'. He said "well then, give her a kiss and hold it for a minute."
He had us both give kisses on the check and did some other fun shots with tinker bell.. tell us to give her that 'come on over here sexy look'! LOL! He was really nice & a lot of fun. And neither he or us cared about the other guests walking around and looking.
We are not big PDA people. But we did walk arm-in-arm fairly often. And always referred to each other as 'my wife' and when we talked to each other it was often 'sweety'. We had meals at a few group tables and talked with other guests in a few of the lines. We never had any issues. (We also never waited in line more then 40 minutes. Guess we had good timing!)
We realize not all Disney World or other Disney trips will be this perfect and amazing. But we are hooked and will for ever be chasing that first 'high'.
We are planning to hit Disney every couple years, at the very least when they ad something new. Totally checking out other Disney adventures too!
