Pre-natal massage spots in NYC

Here is a quick list of NYC spas that accept Spafinder gift certificates (which I can get through my Amex points) and do pre-natal massage:

1. Ritz Carlton Midtown $220/60 min (has steam room)
2. Cornelia spa at the Surrey hotel UES  $175/60 min (has tubs for pre treatment relaxation)
3. Great Jones spa Noho $145/60 min or $205 for 90 min (has water room which you get access to if your treatment is over $100)
4. Guerlain spa at the Waldorf Astoria Midtown $195/50 min or $265/80 min
5. Mandarin Oriental Midtown $325/80 min (has tub, steam room, if you book a half day treatment you get access to the big pool)
6. Peninsula spa Midtown  $205/60 min or $315/90 min (has steam room, pool, tea room)
7. Red Door spa at the Chatwal Midtown $150/50 min (saltwater lap pool and jacuzzi plunge pool)
8. Clay spa Union Square $125/60 min (sauna)
9. Oasis day spa Midtown $130/60 min (prenatal table)

I think to me the Chatwal has the best deal, since I really want the pool experience too.
