WIBU to drop off 6 month old at nursery at 7 even though I don't start work til 9

[Katlow]

Going back to work tomorrow and LO is 6 months old. He's going to nursery a maximum of 3 days a week but it's going to depend on how my husbands shifts fall. I've got no idea what to expect at drop off. I was considering dropping him off early to avoid the hustle and bustle as nursery have said its 'mad' in the morning.
I was thinking I could throw some joggers and a jumper on and drop him off at around 7/7.30 then come home and get ready for work properly.
But then he's woken up this morning (he's usually up at 7) and he's so happy to see me. I don't know how I'd feel about literally getting him up and dressed then straight out the door. :(
How long does nursery drop off usually take? To get in the building etc. I'm so nervous and feeling a little bit guilty.
Bonus points for any answers which tell me how much your 6 month old loved nursery.

My little girl used to love early drop offs. She got to have some quiet time there. She could eat cereal, potter around for an hour then at8:30 everyone turned up!
