We have been to Hampton Inn 3 times in the last 3 years. It has become sort of an annual trip. We enjoy the Hampton, the price is right, breakfast is convient and there is a good selection of food. Best of all the shuttle runs every 30 min. to and from the parks, Hampton is the first on and first off stop. so you always get a seat and on the way back you get off first.
If you have never stayed at a hampton inn, then I should explain that it is not fancy but, plenty clean and comfortable. the rooms have a refridge and microwave for quick easy dinners. The pool is swimable but, nothing fancy or themed.
We are a family of 5 and stay in a room comfortably. We don't spend much time hanging around the room so we don't need fancy though. I have always felt safe and slept well.
As for what Garden Grove is..... you will never know you went from Anahiem to GG. it all runs together because it is such a metropololis. That is the beauty of
Disneyland. It is in the heart of the city.
Hope this helps, have a great time
