We were booked by RCI at this resort; the reception staff were very rude and actually spoke amongst themselves in Thai and made fun of us. The booking was done for 8 people and we had paid for this earlier but were given accommodation for 4. The room comes with a kitchen but we were told we could not cook until we demanded. There were no services that other RCI resorts offer. They did not care that we were guests and did not bother. Only one staff member spoke english and he helped sort some things after we said we would complain to RCI. One woman at the desk actually made faces at us and was very harsh which was very upsetting after a long flight with no sleep. If you are willing to take shabby behaviour, book this hotel. The rooms and beds were comfortable though and did make up for the service.

Like others before us, booked through RCI. Shabby, tired, run down, and DIRTY. The reception staff friendly & helpful at all times. Room recently redecorated and re-fitted but problems with hot water (twice) and refrigerator quickly fixed BUT should have been spotted and fixed prior to our arrival. Terraces were un-swept, tatty and no terrace furniture. No cutlery or crockery, just a kettle, 4 glasses and cups & saucers. No toaster, microwave or any means of preparing food but we did have a dining table & 6 chairs to sit at. Don't really know why!!!! A/C old and tired. TV likewise and kept losing program. Sofa & chairs although newish not comfortable to sit on except for short times.
Pool area was disgusting and pool area toilets even worse. Pool water was so murky you couldn't see the bottom although it was only about 4 ft 6 ins deep. I did jump in just once and got out even more quickly when I saw at close range all the bacteria floating about. At NO TIME did we see or hear any kind of filtration system in operation. In our opinion it should have been closed for health safety reasons.
Restaurant not too bad, but did give my wife food poisoning due to her having a severe allergy to shellfish and them getting our order wrong. Sweet & Sour Prawn instead of Chicken. Luckily after 24 hrs in the wonderful Pattaya Bangkok Hospital all was well.
Resort clientele as far as we could tell was 100% Russian except for us. No other English speaking voices heard during our stay. The only area of resort that seems to get any attention is the Front Lobby which is polished constantly
The Beach does not exist except at low tide and is filthy, full of rubbish, plastic bottles and the calling cards of packs of feral dogs that roam all over it. Horrible!!!!!!!
Despite what their website and RCI reviews say, there is absolutely nothing to do in the immediate vicinity and getting transport to and from the more northern part of Jomtien Beach can be a major problem.
Despite the people being lovely and friendly we think the whole area of Pattaya & Jomtien is awful. The drains stink, there is rubbish everywhere and really is an aura of downmarket shabbinesss and tiredness about the whole place once you look beyond the promised glitz of the new condos being built everywhere, which are principally aimed at the new booming Russian market.
Bottom Line...................Don't go there, that is Pattaya, Jomtien and especially Sigma Resort.

We booked this trip through RCI, a timeshare. Every New Year my boyfriend and I travel and we look forward to this after 11 long months of hard work! But this trip was memorable in a different sort of way... not only were we greeted with obvious disdain, but our room was dirty and did not even contain such basic provisions as a bath towel. The shower had broken tile everywhere, the bedrooms had cracked mirrors and missing bed linens and the beds were unbelievably hard. When we requested towels at the front desk, the associate rolled her eyes! 6 hours later, we finally rec'd our towels. Needless to say, this wasn't our first issue with the resort staff hospitality. We also booked a tour, with a bus that never showed up, and when we asked the concierge to help us contact the company to find out what was going on he simply told us that the phone number was out of the area and could not be called. When we offered to pay for a phone use, he walked away! Who does that?!? The tour company was booked by the resort!!! And when we asked a second staff member to help us, he picked up the house phone and dialed out without questioning a thing.

Breakfast can be included with your stay, but you'll get way more for your money outside or in the town.

Location - nice strip of Jomtien Beach, but fairly far from a lot of Pattaya's main attractions and nightlife and markets. Much better off staying North a bit.

In the end, we only stayed 4 days of the 14 we had booked, at Sigma. We ended up paying considerably less money p/night, for a second resort (Areca Lodge) in the heart of Pattaya. The amenities of Areca Lodge were a vast improvement from Sigma Resort too; with 2 pools, a full spa, and much much more.

I will never recommend Sigma Resort to any fellow travelers. The location and amenities are not worth the price, and the service was the icing on the cake and prompted me to write this review.
