Hi S.,
I am a childcare provider for the past 21 years. Most children under the age of one need a morning nap as well as an afternoon nap. That being said, your little one is sleeping entirely too much during the day. Her morning nap should be somewhere around 30-45 minutes long and her afternoon nap around 1 1/2 to 2 1/2 hours long. My kids usually go down around 9:30 for a short nap (sometimes I only let them sleep 15-30 minutes) and then right back up and into the days' activities. I put all the kids down around 12pm after lunch and we are back up by 2-2:30 which gives us time for an afternoon activity as well as snack.
I would talk to your provider and tell her that you are having difficulty getting your child to bed at night and ask that she please limit her morning nap to 30-45 minutes and then her afternoon nap to no more than 2 hours. It seems to me that your child naps during the times when the provider may be busier with the other children (activities/outdoor play) but your little one SHOULD be involved with those activities on some level. Realistically, by the time a child gets to a year, you should within a month or so be eliminating the morning nap anyway.
I could certainly understand it if your child was 3-4 months, this schedule would seem reasonable, but not at 11 months.
This is just my humble opinion, but a very realistic one, as well. Good luck!

On a side note, I have an issue with "Gamma G's" comments. I have an in-home childcare. Not only do all my children have many, many activities to choose from (puzzles, books, books on tape, sorting toys, lace cards, crayons, scissors, tracing tools, dry erase boards for learning letters/numbers, water play, manipulative play, cooking in a real kitchen, blocks, large motor toys, dollies, trucks, tents, and outside a 20x30 foot sandbox with play equipment, bikes/trikes, balls, sandtoys, trucks, sidewalk chalk, garden, lots of outdoor play) but they also have "real time" with not only children their own age/development stage, but other children, younger and older. We are a real family, learning how to care for one another, every day.
What they ALSO get in my childcare is plenty of one-on-one time with someone who has known them from birth, someone who has held them for every bottle, kissed every boo boo, held them when they are sick, taught them how to use the bathroom, how to share and be a good friend, how to be gentle with a younger sibling and who from day one in my childcare has had time in my lap and arms, with 1000's of kisses and hugs over the course of the time they have spent with me. That, my dear, you CAN'T get at a childcare center with multiple teachers and THAT is ulimately important for a growing child.
Respectfully.
