I'm person number three now that has posted in return who used to frequent Amsterdam. No shots but the girls don't do a good job of providing lube/condoms. They (mostly) have condoms but do you want to depend on the cheapest thing the local pharmacy had that day?? Do what is suggested above for more fun.
The service from the girls is TOTALLY different. You'll like the change

There are many slim girls. My novia is 4'11" 88lbs of the tightest 24-year old body you'll ever see. And there are more like her walking the DR every night.
For your stay, it depends on two things. How long and what you want to do. If your stay is under two weeks, I'd go with hotel. For that subject I'd say the following.
1) If you want to stay in the center of town where all the free-lance action is, less liable to enjoy the comradery CRT guys provide and are willing to pay that price, DR is the place for you. Seems they do not have a personal touch to the service. It is also more difficult to find your way to NF or ZB. Bar Idem isn't too bad but still a walk. All that said with the expectation you'd like to not take a taxi everywhere during the day. At night, it's a must to/from almost any place.
2) If you want to stay a little away from the crowd, have very nice, friendly, secure and fun enviroment where you will meet a lot of great guys in addition to what is in my opinion, better on a girl-to-girl basis "friend", then Sportsmens is your best bet. If you do your research on the board and get the map in the VIP area, you'll be set from Sportsman's. Only a block or five to both NF and ZB down one road. Easier in my opinion for a newbie not to mention the ability to find a wingman in SL. DR is a more difficult five-minute daytime only walk.
3) If you want a little less expensive, La Amistad or Castillo are both good choices. Have the same good location as Sportsman without many of the nicer benefits but still good places to stay.
4) Think Presidente has some value as a nice place to stay and good and close to DR but the dress code and the amount of traffic outside the front door make it more for an experienced guy IMHO.
4) If you wanna go cheap and/or longer than two weeks, look into the cheaper hotels away from the gulch or apartments. More walking and more work finding you way around, but that too can be fun in the daytime. At night, the taxis might take advantage.
I have always stayed for long-term about 10 minute walk to the Gulch. It has been great IMHO. No problems with chicas or anything. Nice neighborhood. You also get to experience more of the local life. Had a great local soda around the corner I ate at every day for a month till it burned down one night

The very nice apartments here run you about $22 dollars a night and are as nice as most hotel hotel rooms.
I've seen the suite in the Sportsman but not in DR. Think you'd be very pleased with the Sportsman's. But if that is your price range, I'd have to recommend ZB with the 'extra benefits' and hospitality from Eddie.
