We were thinking of the maclaren twin techno-so glad we tried it...my 2 yo DS was smushed in it-and he is the size of a 4 yo...so needless to say, I have not found a stroller I like yet for the two of them...we may do 2 separates...I can't find one that fits my DS! Who is 39.5" and about 39 lbs...and an infant who is just 6 weeks!
I did not see your post before I replied to the thread. My daughter is a bit heavier and taller than your son and she loves the Techno. If your son is "smushed" in the Techno, I would suggest the Zooper, E3 (with extra double seat) or a standard double jogging stroller (although jogging strollers are a pain to fold down).
You can always have your single stroller and rent at the parks if you need an extra.
When my son was 3 months old we did Disneyland and I kept him in a carrier about 85% of the time which worked out great. We just traded time in the single stroller between the kids. Good luck and I hope you find the right stroller for your family.
