Brunch reception-enough planned?

Just want to ensure I have done "enough" for our wedding reception to ensure the guests will have fun and that things will run smoothly. We are having a late morning ceremony at 11 am. At 1130 a.m.-12:30 p.m. guests will have cocktail/coffee hour while we get photos done.

Reception to begin at 12:30 p.m. With a plan to serve brunch around that time. At 130 p.m. bride and groom will say speeches and have first dance. Father daughter dance as well. 200ish cake cutting/donut wall. 230 onwards dance and mingle. We have an open bar, mimosa bar, coffee station, DIY photobooth. We wanted an easy going relaxed have fun and mingle without a load of formalities and structure...does this sound ok???

My fiance wanted to bring in a ping pong table of all things...is this necessary??? At this point we are leaning towards not but if it will add more fun element perhaps we should?

. Our photo booth is just DIY/selfie as our photographer didnt provide this. We are already overbudget. Is the use of ppls phones ok or is this lame and should i get a polaroid or bring a universal tablet ppl can use?

Also, we havent got a dj..we just have created playlists, have assigned a music man, and they have a great sound system there. Does this sound reasonable? Am I missing anything? P.s. wedding is in 2 days! 😊
