I agree, I would take your own seat .We took ours when DD was 1.Like the OP said you could just check it in if you dont need it on the plane.I'm pretty sure HL has seats available ,just give a quick reminder call before you leave.
BTW... check out the Baby Stations in the parks...they are awesome if you need to get out of the sun or just need a quiet place to relax w/the babe.They are fully equipped and the CMs are great there.
