Am I autistic enough?

I am going to a zoo with my wife and I have recently been wearing ear plugs in public and my wife says I have been visibly more relaxed when going out with her. The zoo has a sensory accommodation bad but as a grown man I feel like it's unreasonable for me to use it given that all the advertising is that of children. I would definitely benefit from access to quiet rooms and headphones and the small fidgets that they include but can I justify it? Would they judge me or even just deny one to me if I ask? I'm trying to accept my diagnosis and utilize resources that are available to me but I don't feel like I deserve them.

Update: It didn't go well

At the gate I requested the bag and when I went around the corner the person didn't acknowledge me and tried to give the bag to my wife who was behind me. When I grabbed it and started walking away she then asked my dad or my wife to fill out the sign out sheet. I said I could do it and she asked if I was sure. The zoo was great and I did end up using the bag but there were no fidget toys in the bag which I would have liked the stress ball during parts but whatever. The staff was very polite in the park and did not demean me and spoke to me like a person even though I had the sensory badge on. I returned the bag at the front gate and left. I got a call half an hour later asking if my dad or the "lady I was with", even though several times during the interaction at the park a refered to her as my wife, could look for them. When I called back later to make a complaint it turned out the fidget toys were taken out before giving them to me because I "didn't look like I needed them". So luckily I like badgers so the day wasn't completely ruined but it pretty much solidified my fears. Just because I have autism doesn't mean I'm incompetent.
