I like no apostrophe. My reasoning is that the center does not belong to visitors. It is for visitors. So, not a possessive. If it is viewed as possessive, it seems like it should be a plural possessive. So the apostrophe would follow the 'S' rather than precede it.
I also prefer the cleaner look of no punctuation. I never put periods on MD, for example, or on AM and PM, unless a client insists.

How many sign guys does it take to spell check a 2 word sign?
They call them a "Welcome Center" around here. Pretty hard to mess that up.

These questions are not so much grammar questions as style questions.
Regarding time of day:
The Chicago Manual of Style says this: Figures are used in designations of time with a.m. or p.m. (lowercase with periods), the preferred form, or AM and PM (small caps with no periods). Whichever you choose, be consistent throughout the manuscript.
The Oxford Dictionary of American Usage and Style says: The lowercase letters are now more common, and with lowercase the periods are preferred. But many editors prefer the look of AM [in small capitals].
The Associated Press Style guide says all lower case with periods.
Sign painters, historically, do whatever they want.
