You will absolutely not get bored! We took DD at 2 mos, 8 mos, 12 mos, have another trip planned for March, 16 mos. 8 mos has by far been the most fun. She could ride almost everything and wasn't afraid of anything yet. She LOVED all the characters! When we went at 12 mos she only liked Baloo (sp?), King Louie and Marie (from Aristocats).
If you're nursing, practice nursing in public before you go. I'm a pro now but on our first trip it was really awkward; I was either flashing people while DD flailed to get out from under the hot cover or going to the baby care center every 2 hrs. By 8 mos though she was eating table food and only nursing occasionally.
Get yourself a baby carrier, I prefer my Moby wrap. DD doesn't like to sit in her stroller for long periods of time and loves to be held, but my arms don't love that. She'll nap in the Moby, it's comfy for me, I can wear her in a variety of positions, it's in expensive (about $35) and it's one size so you and your DH can share or if you loose, gain weight it will fit. It's also really great for around the house with a newborn, you can get some chores done and have your hands free.
We always take a mid-day break to give DD a good solid nap and some down time from all the stimulation. She was a dream at 8 mos! Not crazy at all for taking your little one! Have fun!!!
