Hello Louise_G_10,
Yes, I was in Universal Studios Singapore yesterday, with the missus, and our 11YO daughter, and despite all the conjecture here, yes...you will have a ball.
We have also been to Universal Studios at both L.A. & Osaka, and while the one in Singapore is still in soft-opening mode (limit 3,000 per day)and not all the rides are open currently, it make for a good day out....especially for the kids.
What is open, is new/fresh and the staff are very hospitable, although still some teething problems around the food outlets...Mels' Diner for example, where we saw one of the attendant/waiters chuck a bit of a wobbley with some customers....but I doubt that she still works there now.
It is a good park, somewhat smaller than it's counterparts, but along the same lines as Disney Sea in Tokyo..if you can make a comparison.
The Shrek 4D routine is directly in-line with Osaka/L.A....and some of the street characters (Marilyn Monroe/Madagascar) are a tad lethargic....due to the heat..?, but the rides are great, and will keep you pumped
Don't forget that when you get your tickets (online, preferably) that you get vouchers for $S10 food, and $S5 gifts...so don't lose these in your purse like my missus did, and then had to try to give them away after we left the park in the afternoon. No one would accept them, despite the fact they were free....because it didn't seem that anything could be free...our mistake, their loss.
Don't expect every ride to be open, whenever you visit, as there will be ongoing construction/safety-level-tests being performed, but the staff are very interactive, and will help you out with any concerns.
Allow at least 6 hours (at this stage...but probably 8 hours in April) for a full day of fun. I'm 56, the missus is 54, and our nipper is 11, and in our opinions.....It is worth it .
Cheers,
Rick
