Step Parents are Special Too - A Wedding Planning Q&A

In the episode Jamie answers questions from members of The Master Plan: -How to explain to older, more traditional family members that we are skipping out on some of the traditional things (bouquet toss, garter toss, party favors, etc) and having a more modern wedding. -My fiancé wants to honor his Mom and Stepmom at the wedding, any suggestions? -How can I support guests with small children and make them feel like they want to stay late? Suggestions? -What's an appropriate amount of time to spend planning your wedding if your date is 18 months out? -Centerpieces - what is a good height or size to make sure that they do not interrupt social time at the table by making it awkward to talk around? -Tent weddings - what are good lighting options and other tent wedding logistics? -Bartender has cautioned against pre-made drink mixes, what are your suggestions for stocking the bar with fun drinks and logistics thoughts? -Hired my photo team through an outsourcing company and now am a little nervous about having a contract with someone whose work I have not seen. Can I request to see a portfolio from the photographer assigned to our wedding? -My fiancé proposed to me at the zoo, how can incorporate this into our wedding subtly and not make our wedding feel theme-y? -Who to invite to the bridal shower if we don't have the exact guest list due to venue space? Do I need to make sure I don't invite anyone who might not be invited to the wedding?
